Investigation of the scale dependence in the MSR and MS ¯ $$ \overline{\textrm{MS}} $$ top quark mass schemes for the t t ¯ $$ \textrm{t}\overline{\textrm{t}} $$ invariant mass differential cross section using LHC data

open access: yesJournal of High Energy Physics, 2023
The computation of the single-differential top quark-antiquark pair ( t t ¯ $$ \textrm{t}\overline{\textrm{t}} $$ ) production cross section at NLO in the fixed-order expansion is examined consistently using the MSR and MS ¯ $$ \overline{\textrm{MS ...

Top quark decays into heavy quark mesons [PDF]

open access: yesPhysical Review D, 1996
For top quark decays into heavy quark mesons $ $ and $\bar{B}_c^*$ , a complete calculation to the leading order both in QCD coupling constant $ _s$ and in $v$, the typical velocity of the heavy quarks inside the mesons, is performed. Relatons between the top quark mass and the decay branching ratios are studied.

Boosted top quark polarization [PDF]

open access: yesPhysical Review D, 2019
In top quark production, the polarization of top quarks, decided by the chiral structure of couplings, is likely to be modified in the presence of any new physics contribution to the production. Hence the same is a good discriminator for those new physics models wherein the couplings have a chiral structure different than that in the Standard Model (SM)

Evidence for four-top quark production in proton-proton collisions at s=13TeV

open access: yesPhysics Letters B, 2023
The production of four top quarks (tt¯tt¯) is studied with LHC proton-proton collision data samples collected by the CMS experiment at a center-of-mass energy of 13 TeV, and corresponding to integrated luminosities of up to 138fb−1.
