Summary: Shared library for Pythia - a simulation program for particle collisions |
Pythia can be used to generate high-energy-physics events, i.e. sets of outgoing particles produced in the interactions between two incoming particles. The objective is to provide as accurate as possible a representation of event properties in a wide range of reactions, within and beyond the Standard Model, with emphasis on those where strong interactions play a role, directly or indirectly, and therefore multihadronic final states are produced. The physics is then not understood well enough to give an exact description; instead the program has to be based on a combination of analytical results and various QCD-based models. Extensive information is provided on all program elements: subroutines and functions, switches and parameters, and particle and process data. This should allow the user to tailor the generation task to the topics of interest. This package provides the shared libraries for pythia.

* Sun Mar 10 2024 Atri Bhattacharya <[email protected]> - Update to version 8.311: * Too many changes to list, see https://pythia.org/history/. - Minor rebasing of patches to apply cleanly against update: * pythia-examples-link-gmp.patch * pythia-honour-env-cxxflags.patch * pythia-remove-rpaths.patch * reproducible.patch - Make doc package noarch. * Wed Jul 26 2023 Atri Bhattacharya <[email protected]> - Update to version 8.310: * Production of quarkonia is now available via the simple timelike shower, see Onia Showers for details. * Added a new feature that allows producing user-defined resonances in hadronic rescattering. Newly added particles can be produced as resonances if they set varWidth = on. * A number of changes have been made to the heavy ion machinery. * Included possibility to sample intermediate photon virtuality also for externally provided events using built-in photon flux for protons. * Included possibility to generate DIS events with a (anti-)neutrino beam. * The TopRecoilHook, formerly available separately, has now been integrated into the SimpleTimeShower. * Introduced a new use plugin system, see Plugins for details. * The arguments to the setSigmaPtr method are now shared pointers. Additionally, addSigmaPtr has been introduced with the previous behaviour of setSigmaPtr, and the new setSigmaPtr overrides all previously added pointers. * A similar change has been made for the setResonancePtr method with the addition of the addResonancePtr method. * The new Logger class now handles printing such as initialization information and diagnostic messages. For more information about this class, see the Logging page. * The new BeamSetup class has been introduced to handle the beam configuration, including initializing and changing beam identities, kinematics and parton distributions. * Modified interface to LHAPDF6 to allow for multi-threading. * Updated the Python interface to use pybind11 version 2.10.4 which is compatible with Python 3.11. * Fix for the Python interface working with gcc13. * Fixed a bug in the Python interface which prevented main162.py from running correctly when passing a custom function for initialization. * Updated the Lambda_b0 lifetime to c*tau = 0.44 mm. The value was rounded to two significant digits since PDG and HFLAV do not quite agree to three digits. * Included several small fixes in response to running an LLVM static code analysis. * Fixed out-of-range access when calling Hist::getYMin and Hist::getYMax for a histogram that has not been booked. * Fixed BeamRemnants:unresolvedHadron option that was broken and had no effect since 8.307. * Removed use of simple-template-ids in SusyLesHouches.h to make compliant with C++20. * Fixed dipole sorting behaviour in ColourReconnection which resulted in an ordering that depended on the current memory state of the program. * Changed the default for Parallelism:balanceLoad to on and updated the documentation. This ensures each thread will always generate the same number of events. * Added the += notation for settings vectors, as well as the include = fileName directive, which allows for additional settings files to be directly read in. * Fixed a bug in the bookkeeping the number of hadrons in the string fragmentation. - Major rebase of pythia-remove-rpaths.patch for updated version. * Sun Feb 27 2022 Atri Bhattacharya <[email protected]> - Update to version 8.307: * Extensions to the hadronic cross sections and beam types used for hadronic rescattering and cascades in the atmosphere. * Improvements for hidden valley scenarios. * A new framework for parallelisation (in addition to the existing openMP option). * A number of other technical improvements and bug fixes (full list here: https://pythia.org/history/index.html). - Minor rebase of patches to apply cleanly, without fuzz. * Wed Jan 05 2022 Atri Bhattacharya <[email protected]> - Drop HepMC2 dependency and build without hepmc2 support; largely superseded by HepMC(3) and this change allows Leap 15.x builds to proceed without HepMC2-HepMC conflicts. - Add BuildRequires: fastjet-plugin-siscone-devel which is needed for one of the tests (test number 111). * Sun Dec 12 2021 Atri Bhattacharya <[email protected]> - Update to version 8.306: * Fixed the incorrect scale being set when applying the POWHEG veto, i.e. main31.cc. Note that the number of emissions is correct in 8.303, but is incorrect in 8.304 and 8.305. * Fixed repeated initialization causing an ever expanding physics pointer list in the main Pythia class. * Fixed issue for HepMC output from Vincia, which would previously issue warnings about inconsistent mother/daughter relationships. * Removed assert statements from Angantyr. * Shortened Pythia constructor header. - Rebase pythia-honour-env-cxxflags.patch and pythia-makefile-destdir-support.patch to apply cleanly. - Major rebase of pythia-remove-rpaths.patch for updated version. - Drop patch not required any more: * pythia-disable-example23-req-MixMax_h.patch: Examples can now be disabled by passing options to the run script. - Change BuildRequires to pkgconfig based ones wherever appropriate. - More examples need linking against gmp explicitly: add fixes for all necessary examples to patch pythia-example71-link-gmp.patch and rename it to pythia-examples-link-gmp.patch. - Build with Rivet and HepMC(3) support: add HepMC-devel, pkgconfig(rivet) BuildRequires. - Update URL and source URL in keeping with upstream. - Minor improvements to package summaries. - Run spec-cleaner for minor cleanups. * Fri Apr 16 2021 Bernhard Wiedemann <[email protected]> - Fix build for Leap 15.3 * Thu Jan 07 2021 Andreas Schwab <[email protected]> - Compile with %optflags * Mon Jan 04 2021 Bernhard Wiedemann <[email protected]> - Add reproducible.patch to drop build date (boo#1047218) * Sun Jan 03 2021 Atri Bhattacharya <[email protected]> - Update to version 8.245: * Significant speedup of parton distribution handling. * Several fixes to avoid out-of-bound evaluation of vectors in the merging code. * Several fixes to correctly handle CKKW-L merging of EWkino- and higgsino-processes have been included. * Include the functionality for MC@NLO-Delta matching with aMC@NLO. * Further bug fixes for the hard process name handling for weak-boson-fusion-like processes, that led to an incorrect counting of additional emissions. * Small fixes to history construction in the presence of multiple resonances. * The primordial kT for LHE files is now set by the BeamRemnants:primordialKThard average value, rather than the LHE scale, since the latter may be quite low e.g. in the POWHEG approach. * The problem of "dangling" gluons causing changing color flows in SimpleTimeShower for top decays is now fixed. * Extra check added to SimpleSpaceShower for the case where a small daughter PDF value can lead to an infinite loop if PDF variations are switched on. * Bug fixed in the new possibility to let particles with narrow widths (such as onia states) obtain a simple Breit-Wigner distribution, specifically for MPIs, introduced in 8.240. * An indexing bug, for the scattering lepton in DIS events with photon radiation allowed, has been fixed. * Added a few copy constructors to match corresponding assignment operators, to avoid warnings for some compilers. * Small fix in cross section calculation of main89.cc. * Fixes in configure and examples/Makefile to have ROOT examples work again. * main**.cmnd, ** = 81-84, 87-88 have been slightly modified such that linking to LHAPDF6 is not required by default. * A bug in the XML-to-HTML conversion has led to the indiscriminate removal of "more" from the HTML manual, notably in Pythia::moreDecays(). - Add patches: * pythia-example71-link-gmp.patch: Fix building example 71 by adding -lgmp to the linker flag. * pythia-disable-example23-req-MixMax_h.patch: Drop a test that requires the non-free MixMax.h header (which we delete). - Use autopatch to setup source dir and apply patches automatically. * Sun Mar 01 2020 Atri Bhattacharya <[email protected]> - Update to version 8.244: * The combination of weight variations, within the context of uncertainty bands, has not been well documented and therefore prone to misunderstandings. Now the behaviour of Info::getGroupWeight() has been made transparent, and the documentation in Variations has been improved. The main121.cc example has been modified accordingly. * Restore the capability to set width and lifetime of a resonance separately (see change in 8.240). Now the lifetime is set from the width only if the allowCalc() method of the resonance class returns true. * Updated handling of Powheg files, such that files with multiple/variable number of real emissions can be handled. The default value of the POWHEG:nFinalparameter has been changed to -1, see the POWHEG Merging documentation. * Limit the amount by which transverse smearing of the space-time quark-antiquark string breakup vertices can give large shifts, which may translate into unreasonably long invariant times being assigned to primary hadron production vertices. This is regulated by the new HadronVertex:maxSmear parameter. Even so, large hadron production invariant times may still occur occasionally by imperfections in the reconstruction around multiple gluon corners, so HadronVertex:maxTau gives the possibility to reject the hadrons of such a parton system and try again. Also some other related changes. * Fixes for consistent storage of production vertices in units of mm. Thanks to Christopher Plumberg. * Number of weights in info reset to 1 for each new init call. - Drop manual fixes in specfile that are no longer needed: * No unusual hidden files to delete. * Buildroot doesn't get copied into config files. * No more spurious exec permissions in plain files.
