IFT femtoscopy lines

Thomas Boettcher requested to merge thboettc_femtoscopy_lines into master

Summary: This MR adds 35 HLT2 lines (3 full event and 32 TURBO) selecting a total rate of about 1 kHz (assuming 1 MHz input rate and no HLT1 filter; the actual rate will be substantially lower due to the Hlt1L02ppi filter).

Add lines for nucleon-hyperon and hyperon-hyperon femtoscopy studies. The aim is to study femtoscopic correlations between particle pairs using 2023 data. As a result, we are focusing on pairs that will give us adequate statistics with low luminosity and that can make use of a high-rate HLT1 inclusive \Lambda line, Hlt1L02ppi. We also plan to include some initial \Lambda-charm lines, as these benefit from Hlt1L02ppi and will serve as a precursor for future measurements studying exotic hadrons using femtoscopic correlations.

Lines include:

  • inclusive (prescaled) \Lambda\to p\pi^-
  • inclusive (prescaled) \Xi^-\to\Lambda\pi^-
  • inclusive (prescaled) \Omega^-\to\Lambda K^-
  • p-\Lambda
  • p-\overline{\Lambda}
  • \Lambda-\Lambda
  • \Lambda-\overline{\Lambda}
  • p-\Xi^-
  • p-\Xi^+
  • \Xi^--\Xi^-
  • \Xi^--\Xi^+
  • p-\Omega^-
  • p-\Omega^+
  • \Omega^--\Omega^-
  • \Omega^--\Omega^+

TODO

  • Add lines for pairs of different hyperons (e.g. \Lambda-\Xi^-)
  • Add lines for \Lambda-D^{0,\pm}_{(s)} and \Lambda-\Lambda^{\pm}_c
  • Add configuration with full-rate low-k* lines and prescaled high-k* lines
  • Determine rates and prescales
