SensCalc

Please always switch to the up-to-date version! 

A public and unified evaluator of sensitivities of lifetime frontier experiments to feebly interacting particles. Based on Mathematica. For details, see the accompanying papers 2305.13383, 2409.11096, and the .pdf manual included among the files.

Currently, it is a beta version, so there may be bugs. You are very welcome to write about them!

The list of changes compared to the previous version (v.1.1.2.1):

    1. Added descriptions of proton bremsstrahlung by Foroughi-Abari&Ritz, together with uncertainties.
    2. Added the revised production via mixing for dark photons.
    3. Added EventCalc - Monte Carlo sampler based on SensCalc.  
    4. Fixed the bug with the transverse spatial separation cut (previously, it was always assumed that the event passes this cut).
    5. Added matrix elements for 3-body decay modes of dark photons (previously, flat matrix elements were assumed).
    6. Split jet decays of different LLPs into separate modes and computed pregenerated pythia phase space. Say, the previous "Jets-light" for dark photons (including decays into various quarks) has been split into "Jets-uu", "Jets-dd", "Jets-ss".
    7. Added partially revised constraints on ALPs coupled to fermions following 2310.03524.
    8. Fixed bug for the ALPs coupled to photons via photon fusion for LHC and FCC-hh in notebook 2
    9. Add fixes of many bugs appearing because some commands in Mathematica > 13.2 are evaluated differently
    10. Added ESS experiments: SHINESS and SHINESS-forward
