  • 1.14.1

    1ed20f21 · Bump version 1.14.0 -> 1.14.1 ·
    Release: 1.14.1 
    Version 1.14.1

ADDED

- Add `[events] cache_size` setting to set the events cache size;
  this is currently only used when writing LHEH5 files
  ([!326](https://gitlab.com/spice-mc/pepper/-/merge_requests/326))

- Add topic guide on random numbers and reproducibility in the manual
  ([!325](https://gitlab.com/spice-mc/pepper/-/merge_requests/325))

FIXED

- Fix dropping of info when shuffling LHEH5 files
  ([fb57d2a4](https://gitlab.com/spice-mc/pepper/-/commit/fb57d2a4a495d44d81f5066cb93fd9810826a982),
  [!324](https://gitlab.com/spice-mc/pepper/-/merge_requests/324))
- Use process-dependent LHEH5 shuffling length
  ([249a8fad](https://gitlab.com/spice-mc/pepper/-/commit/249a8fad40ef28790c74860936e07210610d4b27),
  [!324](https://gitlab.com/spice-mc/pepper/-/merge_requests/324))
- Fix issues with reproducibility across cache states
  ([!325](https://gitlab.com/spice-mc/pepper/-/merge_requests/325))
  - Store cache floats at full double precision
  - Distribute book-kept trials when not writing zero-weight events
    over a batch reproducibly
  - Reset the RNG after filling the cache when using `fill_lheh5_buffer`
- Remove correlation in book-kept trials distribution
  when using `fill_lheh5_buffer`
  ([!325](https://gitlab.com/spice-mc/pepper/-/merge_requests/325))

PERFORMANCE

- Use a larger event cache default when writing LHEH5 files
  ([!326](https://gitlab.com/spice-mc/pepper/-/merge_requests/326))
- Lay out the HDF5 data sets in LHEH5 files in chunks of about a MB
  ([!326](https://gitlab.com/spice-mc/pepper/-/merge_requests/326))

  • 1.14.0

    641cdad2 · Bump version 1.13.1 -> 1.14.0 ·
    Release: 1.14.0 
    Version 1.14.0

ADDED

- Add massive Q-V-Q vertex, adding support for Vbb and Vtt processes
  ([!312](https://gitlab.com/spice-mc/pepper/-/merge_requests/312))

- Add a `Pepper::Process` constructor overload taking a per-process
  `n_max_quark_pairs` limit, so a host application driving several jet
  multiplicities can restrict each of them separately instead of only
  run-wide via `[main] n_max_quark_pairs`; this also adds missing documentation
  for the setting
  ([!321](https://gitlab.com/spice-mc/pepper/-/merge_requests/321))

- Add process group files for definite-charge W-boson production,
  selectable via the `ppwm` and `ppwp` base specifiers
  (with up to six additional jets),
  next to the existing charge-summed `ppev` specifier
  ([!323](https://gitlab.com/spice-mc/pepper/-/merge_requests/323))

- Add a process group file for pp -> 6j,
  along with the color factor files needed for this process
  ([479c65b3](https://gitlab.com/spice-mc/pepper/-/commit/479c65b3eaf93a7331e4604cc4282c496a13143b))

- Add description attribute to the file metadata
  ([!320](https://gitlab.com/spice-mc/pepper/-/merge_requests/320))

FIXED

- Refer to the photon as "A" and parse particle names case-insensitively
  ([1be71bbd](https://gitlab.com/spice-mc/pepper/-/commit/1be71bbdb1dbb3b5014a8fd3b973061b2096fe0f))

CHANGED

- **Breaking:** Revert the 2.3.0 LHEH5 change and count all particles,
  incoming and outgoing, in `npLO` again, bumping the format version to 2.6.0.
  This restores agreement with Sherpa's LHEH5 writer
  and with Pepper's own `Event_reader`. Counting all particles is however
  inconsistent with the definition in arXiv:2309.13154, so that's a trade-off.
  However, ultimately we deemed it more important to be consistent
  with actual implementations.

  • 1.13.1

    21d11fb0 · Bump version 1.13.0 -> 1.13.1 ·
    Release: 1.13.1 
    Version 1.13.1

ADDED

- The `init` data set now carries `generatorName`, `generatorVersion` and
  `phasespaceGenerator` attributes, in the spirit of the `<generator>` tag
  of the LHEF v3 specification, so that an event file states which program
  produced it and how its phase-space points were sampled.
  ([5f1a22bd](https://gitlab.com/spice-mc/pepper/-/commit/5f1a22bdbe92630bb037315620d46ffc2d91c6dc),

FIXED

  instead of per active helicity configuration
  ([c5a786b3](https://gitlab.com/spice-mc/pepper/-/commit/c5a786b3b136a28b37e6b0e85f0a5cf12e69e1ba))

- Fix missing Chili outlier filtering when reading in events
  ([!311](https://gitlab.com/spice-mc/pepper/-/merge_requests/311))

- Fix bug in the application of cuts for W boson resonances
  ([d9e0dde5](https://gitlab.com/spice-mc/pepper/-/commit/d9e0dde519eed456c4c9db210649402d1d3600dc))

  ([cd784004](https://gitlab.com/spice-mc/pepper/-/commit/cd784004ab1438ad08e4892e2bccf3013c0784bb))

- Improve lookup of color files, by also considering equivalent flavor labelings
  ([cdb29905](https://gitlab.com/spice-mc/pepper/-/commit/cdb29905901bf117a62ecc8994465feecc2dab6d))

- Fix handling of dead di-boson phase-space points;
  before they were still processed (reducing performance),
  and they were wrongly added to the number of nonzero points
  ([052c3edc](https://gitlab.com/spice-mc/pepper/-/commit/052c3edc40def9126abbe862c6f7b4e772bbd4ee))

PERFORMANCE

- Fix the upper mass bound in the resonance phase-space sampling;
  this did not bias cross sections,
  but it did reduce phase-space sampling efficiency by a small fraction
  ([0ab5c95f](https://gitlab.com/spice-mc/pepper/-/commit/0ab5c95fb1f93fcda123ee2d86471524d4289484))
