Name: python-SHERPA-MC Distribution: openSUSE Tumbleweed
Version: 2.2.6 Vendor: openSUSE
Release: 3.1 Build date: Mon Sep 9 13:16:43 2019

Summary: Python extensions for SHERPA-MC
Sherpa is a Monte Carlo event generator for the Simulation of
High-Energy Reactions of PArticles in lepton-lepton, lepton-photon,
photon-photon, lepton-hadron and hadron-hadron collisions. It provides
complete hadronic final states in simulations of high-energy particle
collisions. The produced events may be passed into detector
simulations used by the various experiments. The entire code has been
written in C++.

This package provides the python extensions for Sherpa.

* Thu Jan 24 2019
  - Update to version 2.2.6:
    * Add initial-state p_z and inelasticity selectors for DIS (#80)
    * Improve the reweighting to include the local K=BBar/B factor
      in MEPS@NLO runs (#73)
    * Improve treatment of the shower reweighting scale cut-off, it
      is now applied also when reweighting AlphaS and the PDFs in
      the CKKW clustering sequence (also mentioned in #73)
    * Adapt status=4 convention in the short HepMC output (#79)
    * Compute approximate NLO EW corrections (and subleading orders)
      as on-the-fly alternative event weights (#41). See Example in
      Manual for details. Currently only works with a
      soon-to-be-released version of OpenLoops.
    * Add a filter between the perturbative and the non-perturbative
      event phase, which can be used to reject events with
      parton-level cuts (!94)
    * Bug fixes:
    - Fix NLO and Variable Selector routines (#70, #88)
    - Fix unweighting treatment for the LocalKFactor (and its
      on-the-fly variations) in negative events (#94)
    - Fix argument validation in
    - Fix core scale setter for DIS when the incoming particles
      are ordered ep instead of pe and adapt it for ee->xy (where
      xy is not a quark pair) (!81)
    - Fix strong coupling reweighting in merging runs in cases
      where nothing was clustered (#66)
    - Fix beam remnants for DIS setups

  - Drop SHERPA-MC-fix_arm_build.patch: fixed upstream.
  - Rebase SHERPA-MC-no-return-in-non-void-function.patch: partially
    upstreamed; fix new error introduced.
* Wed Apr 25 2018
  - Update to 2.2.5:
    * Interface changes
    - Add preliminary support for HepMC3 (this interface is still
      being tested)
    * New features
    - Improve decay showering off top quarks
    - Improve single-top support and add examples and documentation
      for its production channels
    - Improve hadronisation and hadron decays for heavy flavour
    - Introduce a user hook framework which allows users to easily
      event generation afterburners, see Examples/Userhook
    - Add settings to output ME-only on-the-fly variations (along with
      the full ones):
    - New cut-off for parton-shower reweighting:
      CSS_REWEIGHT_SCALE_CUTOFF=<pt_min>, default: 5 GeV2
      this is more generally applicable than using a cut-off on the
    number of reweighted emissions
    - Improve support for on-the-fly variations of clustering steps
      (reweight each step locally instead of doing it globally)
    * Bugfixes
    - Fix issue with the overweight treatment for negative weights
    - Add missing shower weight in some event outputs, e.g. when using
      `OUTPUT HepMC...[]`
    - Fix issue with the overweight threshold for on-the-fly variations
    - Fix issue with non-trivial beam spectra handling
    - Fix possible issues with electron-"PDF" initialization
    - Fix issue with the ISR-channel threshold for leptonic collider
    - Fix X/Y functions in METOOLS (this is relevant for hadron decays)
    - Fix crash in decay-channel sorting
    - Fix crash when using EVENT_TYPE=HadronDecay
    - Fix issue with CSS strong coupling values when using non-trivial
      scale factors
    - Fix issue with QSF variations for real emission calculations with

      kinematics occur

* Fri Sep 08 2017
  - Upstream released a new 2.2.4 tarball, so refresh sources.
* Sat Sep 02 2017
  - Update to version 2.2.4:
    * Interface Changes:
    - New default parameters for hadronisation model to improve
      heavy flavour production fractions and meson/baryon ratios.
    - Updates to Recola interface with some new parameter (names),
      please refer to the manual.
    - Make STRICT_METS the default scale setter to guarantee full
      scale setting accuracy for unweighted events.
    * New features
    - Availability of DIRE NLO parton shower (cf.
      arXiv:1705.00742). This is not (yet) the default shower, in
      particular not in NLO-merged configurations.
    - Higher numerical stability in parton shower kinematics
    - Add OVERWEIGHT_THRESHOLD allowing user to cap maximal weight
      during event generation (cf. manual).
    - Avoid spuriously large weights in NLO-merged samples due to
      instable PDF ratios.
    - Add interface for hadron-level selectors.
    - Add Max_N_TChannels option in Amegic.
    - Add possibility to identify partons which originate in the
      hard decay handler.
    - Restructure gzip support such that it can be switched off at
      runtime (USE_GZIP).
    - Enable on-the-fly reweighting for calculations with the
      Higgs (Interference) add-on for HIGGS_INTERERENCE_MODE 1, 2,
      3 or 4.
    * Bugfixes
    - Bugfix in NLO-matched parton shower emission for non-trivial
      colour structures like in V+2j@NLO. This fixes an eta
      asymmetry which was visible at the ~2% level in such
    - BSM models through UFO: fix running coupling behaviour and
      treatment of exotic color octets.
    - Bugfix in random generator for Poisson distributions with
      large mean values.
    - Bugfixes for segfaults and compiler warnings with gcc 7.1.
    - Bugfix for colour assignment in clustering for loop-induced
      merged processes.
    - Bugfix for decay showering in conjunction with NLO+PS
  - Change BuildRequires HepMC-devel to HepMC2-devel: not compatible
    with HepMC >= 3.0.
  - Rename libSHERPA-MC-config to libSHERPA-MC0-config that follows
    the shared lib versioning. In addition the file is
    also renamed to follow the shared lib version to make it
    possible to install multiple versions of the shared lib.
  - Rebase SHERPA-MC-no-return-in-non-void-function.patch and add
    fixes for one more function showing the same issue in version
  - GCC >= 6.0 required, build fails with older GCC for openSUSE <=
* Fri Apr 28 2017
  - Update to version 2.2.3:
    * Support for the Recola one-loop generator for QCD corrections.
  - Add SHERPA-MC-no-return-in-non-void-function.patch -- Fix a
    non-void (bool) function that was not returning any data to
    return "true".
* Mon Feb 13 2017
  - Shared library package must only contain time-unique names;
    split off libSHERPA-MC-config.
* Thu Feb 02 2017
  - use individual libboost-*-devel packages instead of boost-devel
* Thu Nov 10 2016
  - Update to version 2.2.1:
    * Incoporation of approximate NLO EW corrections in MEPS@NLO
      simulation as described in arXiv:1511.08692
    * On-the-fly renormalisation and factorisation scale, PDF and
      alpha_s variations in the matrix elements for LO, LOPS, NLOPS,
      MEPS, MENLOPS and MEPS@NLO simulations as described in
  - Changes from version 2.2.0: See
  - Drop gcc6_char_cast.patch; incorporated upstream.
* Sun Jun 19 2016
  - RPM group classification
  - run install_info in preun to avoid errors of missing files
  - Shared library subpackage is supposed to include the number
* Thu Jun 16 2016
  -  new gcc6_char_cast.patch
