Hunting down the X17 boson at the CERN SPS
E. Depero, Yu. M. Andreev, D. Banerjee +53
Recently, the ATOMKI experiment has reported new evidence for the excess of events with a mass 17 MeV in the nuclear transitions of He, that they previously obs…
General recipe to form input space for deep learning analysis of HEP scattering processes
Andrei Chernoded, Lev Dudko, Georgi Vorotnikov +4
Deep learning neural network technique (DNN) is one of the most efficient and general approach of multivariate data analysis of the collider experiments. The important step of the…
Improved limits on a hypothetical X(16.7) boson and a dark photon decaying into pairs
D. Banerjee, J. Bernhard, V. E. Burtsev +51
The improved results on a direct search for a new X(16.7 MeV) boson which could explain the anomalous excess of pairs observed in the excited 8Be nucleus decays ("Berilliu…
Measurement of the top quark pair production cross section in dilepton final states containing one lepton in pp collisions at 13 TeV
CMS Collaboration
The cross section of top quark pair production is measured in the final state, where ref…
Dark matter search in missing energy events with NA64
D. Banerjee, V. E. Burtsev, A. G. Chumakov +48
A search for sub-GeV dark matter production mediated by a new vector boson , called dark photon, is performed by the NA64 experiment in missing energy events from 100 GeV elect…
Measurement of normalised multi-differential cross sections in pp collisions at TeV, and simultaneous determination of the strong coupling strength, top quark pole mass, and parton distribution functions
CMS Collaboration
Normalised multi-differential cross sections for top quark pair () production are measured in proton-proton collisions at a centre-of-mass energy of 13 TeV…
