Bottom-quark production at hadron colliders: fully differential predictions in NNLO QCD
Journal of High Energy Physics, 2021 We report on the first fully differential calculation of the next-to-next-to-leading-order (NNLO) QCD radiative corrections to the production of bottom-quark pairs at hadron colliders.

Heavy Quark Phenomenology from Lattice QCD [PDF]
, 2000 Recent results relevant for the B-physics phenomenology, obtained from lattice QCD simulations by the APE Collaboration, are reviewed. This includes the B0-B0bar mixing amplitude, B-> pi semileptonic decay and the relative width difference of B0_s mesons,

Analytic results for Sudakov form factors in QCD
Journal of High Energy Physics, 2022 Sudakov form factors appear ubiquitously in factorized cross sections where they allow one to resum large logarithms to all orders in perturbation theory.

Positivity bounds on parton distributions at large N_c [PDF]
, 2002 Positivity bounds for twist-two parton distributions in multicolored QCD are stronger than their analogs at finite $N_c$. They include the enhanced large $N_{c}$ version of Soffer inequality. These bounds are compatible with the DGLAP evolution to higher

Standard Model prediction of the B c lifetime
Journal of High Energy Physics, 2021 Applying an operator product expansion approach we update the Standard Model prediction of the B c lifetime from over 20 years ago. The non-perturbative velocity expansion is carried out up to third order in the relative velocity of the heavy quarks. The

Gribov's Confinement Scenario [PDF]
, 2000 I give a brief account of Gribov's scenario of supercritical charges in QCD. Gribov's equation for the Green function of light quarks and its derivation from the corresponding Dyson-Schwinger equation are described.

Colour and logarithmic accuracy in final-state parton showers
Journal of High Energy Physics, 2021 Standard dipole parton showers are known to yield incorrect subleading-colour contributions to the leading (double) logarithmic terms for a variety of observables. In this work, concentrating on final-state showers, we present two simple, computationally

Composite phenomenology as a target for lattice QCD [PDF]
Proceedings of The 36th Annual International Symposium on Lattice Field Theory — PoS(LATTICE2018), 2018 Some recent beyond Standard Model phenomenology is based on new strongly interacting dynamics of $SU(N)$ gauge fields coupled to various numbers of fermions.
