Luminosity measurement with the LHCb RICH detectors in Run 3 Open
The LHCb Ring-Imaging Cherenkov detectors are built to provide charged hadron identification over a large range of momentum. The upgraded detectors are also capable of providing an independent measurement of the luminosity for the LHCb exp…

Performance of the LHCb RICH detectors during LHC Run 2 Open
The performance of the ring-imaging Cherenkov detectors at the LHCb experiment is determined during the LHC Run 2 period between 2015 and 2018. The stability of the Cherenkov angle resolution and number of detected photons with time and ru…

$\\kappa$-deformed complex scalar field: conserved charges, symmetries\n and their impact on physical observables Open
In this paper we revisit the model of $\\kappa$-deformed complex scalar field.\nWe find that this model possesses ten conserved Noether charges that form,\nunder commutators, a representation of (undeformed) Poincar\\'e algebra. It\nfollow…

A study of muon-electron elastic scattering in a test beam Open
In 2018, a test run with muons in the North Area at CERN was performed, running parasitically downstream of the COMPASS spectrometer. The aim of the test was to investigate the elastic interactions of muons on atomic electrons, in an exper…

arXiv : A Comparison of CPU and GPU implementations for the LHCb Experiment Run 3 Trigger Open
The LHCb experiment at CERN is undergoing an upgrade in preparation for the Run 3 data taking period of the LHC. As part of this upgrade the trigger is moving to a fully software implementation operating at the LHC bunch crossing rate. We …

Correlations and ridge in<i>p</i>Pb collisions in the LHCb Experiment Open
The LHCb experiment, besides its main programme concerning flavour physics performs also very well as a general purpose forward detector, covering the pseudo-rapidity range from 2.0 to 5.0. Exploiting the experiment’s unique geometry, the …
