Emerging jets at Long Lived Particle Experiments

Current LLP Detectors Implemented

Within Detector_sims you'll find detector simulations written in Mathematica notebooks:

• AL3X.nb AL3X is a set of cyclindrical detectors at the ALICE experiment IP. Specs based on https://arxiv.org/abs/1811.01995
• ANUBIS.nb ANUBIS is a transverse cyclindrical detector proposed at ATLAS or CMS. Specs based on https://arxiv.org/abs/1909.13022
• CODEXB.nb CODEXb is a transverse box detector proposed near the LHCb IP. Specs based on https://arxiv.org/abs/1911.00481
• FASER.nb FASER is a highly forward cyclindrical detector planed at the ATLAS IP. Specs based on https://arxiv.org/abs/1901.04468
• FORMOSA.nb FORMOSA is a forward box detector using a LHC IP. Specs based on https://arxiv.org/abs/2010.07941
• MATHUSLA.nb MATHUSLA is a large transverse box detector above the ATLAS IP. Specs based on https://arxiv.org/abs/1901.04040
• SHIP.nb SHIP is a fixed target oblate cyclindrical detector using the SPSS IP. Specs based on https://arxiv.org/abs/2009.06003

t-channel production

Within Feynrules you'll find A t-channel production model file used for proper forward scattering where the dark and visible sectors interact through a new scalar bi-fundamental.

The bi-fundamentals are denoted with su11, su12, su21, su22..., where u etc explicitly specifies the QCD flavour index and the numbers are the explicit dark non-Abelian group indices. Similarly, the dark quarks are labeled as qv11, qv12, qv21, qv22.

Pythia Example

• With the proper MAKE script

make EJListOut

• Run the script using model file model_script_X.dat

./EJListOut model_script_X.dat
