Measurement of the inclusive $$ \mathrm{t}\overline{\mathrm{t}} $$ production cross section in proton-proton collisions at $$ \sqrt{s} $$ = 5.02 TeV [PDF]

open access: yesJournal of High Energy Physics, 2022
The top quark pair production cross section is measured in proton-proton collisions at a center-of-mass energy of 5.02 TeV. The data were collected in a special LHC low-energy and low-intensity run in 2017, and correspond to an integrated luminosity of ...

Recent Development and Results with the MERLIN Tracking Code [PDF]

open access: yes, 2017
MERLIN is a high performance accelerator simulation code which is used for modelling the collimation system at the LHC. It is written in extensible object-oriented C++ so new physics processes can be easily added.
