Constraining four-heavy-quark operators with top-quark, Higgs, and electroweak precision data
Stefano Di Noi, Hesham El Faham, Ramona Gröber +2
We establish constraints on the dimension-six four-heavy-quark operators in the Standard Model Effective Field Theory (SMEFT) by synthesising LHC measurements of top-quark and sing…
Triple-gauge couplings in LHC diboson production: a SMEFT view from every angle
Hesham El Faham, Giovanni Pelliccioli, Eleni Vryonidou
This study explores fully leptonic WZ and WW production at the LHC within the SMEFT framework at NLO in QCD, focusing on both CP-even and CP-odd triple-gauge-coupling dimension-six…
Electroweak corrections in the SMEFT: four-fermion operators at high energies
Hesham El Faham, Ken Mimasu, Davide Pagani +3
In the Standard Model (SM), electroweak (EW) corrections become significant at high energies, particularly at the tera-electronvolt scale and beyond, due to the presence of Sudakov…
Elliptic anisotropy measurement of the f(980) hadron in proton-lead collisions and evidence for its quark-antiquark composition
CMS Collaboration
Despite the f(980) hadron having been discovered half a century ago, the question about its quark content has not been settled: it might be an ordinary quark-antiquark ($\mathr…
Multiplicity dependence of charm baryon and charm meson production in pPb collisions at = 8.16 TeV
CMS Collaboration
Measurements of the production yields of charm baryons () and charm mesons (D) in proton-lead collisions at a nucleon-nucleon center-of-mass energy of 8.16 TeV…
Search for fractionally charged particles in proton-proton collisions at = 13 TeV
CMS Collaboration
A search is presented for fractionally charged particles with charge below 1, using their small energy loss in the tracking detector as a key variable to observe a signal. The a…
