Software

SUBA-Jet

Monte Carlo code implementing a new model for jet quenching from coherent radiation, simulated as a perturbative final-state vacuum parton shower followed by a medium-induced shower originating from elastic and radiative collisions with the medium constituents. Can be interfaced with vHLLE for realistic simulation of an expanding medium.

EPOS4+JETS

The implementation of the SUBA-Jet model within the new EPOS4 Monte Carlo framework. The initial state, fluid simulation, and hadronisation will be provided by EPOS4. The SUBA-Jet parton shower will run concurrently with the hydro evolution in EPOS4.

Helac+OpenLoops

Novel Monte Carlo framework built to handle NLO QCD calculations of the interference between loop-induced and tree-level processes. The phase space generation is performed using Kaleu, and the dipole subtraction has been derived from the implementation in Helac-Dipoles. All tree and loop matrix elements are obtained with a modified version of OpenLoops.

Presented in my PhD thesis and in arXiv:2309.16759 [hep-ph].

H1jet

H1jet is a fast code that computes the total cross section and differential distribution in the transverse momentum of a colour singlet. H1jet can be used to assess deviations of selected new physics models from the Standard Model behaviour, as well as to quickly obtain distributions of relevance for Standard Model phenomenology.

Source code available on Hepforge and GitHub.

An interactive version is available at H1jet Online.
