Analytic result of Higgs boson decay to gluons with full quark mass dependence

open access: yesPhysics Letters B
We report the first analytic calculation of the Higgs boson decay width to gluons up to next-to-leading order in quantum chromodynamics including full dependence on the bottom and charm quark masses.

$B_c$ enhancement with non-thermalized bottom quarks in nuclear collisions at Large Hadron Collider [PDF]

open access: yes
We study $B_c$ production in high-energy nuclear collisions in a transport approach with dissociation and regeneration at finite temperatures. Due to the rare production in p+p collisions and the strong combination of uncorrelated $c$ and $\bar b$ quarks

Fragmentation of bottom quarks in top quark decay

open access: yes, 2004
We review the main aspects of the fragmentation of bottom quarks in top quark decay. The NLO b-quark energy spectrum presents large mass logarithms ln(m_t^2/m_b^2), which can be resummed by the use of the approach of perturbative fragmentation functions.

Resummed jet rates with heavy quarks in e+ e- collisions

open access: yes, 2003
Expressions for Sudakov form factors for heavy quarks are presented. They are used to construct resummed jet rates in electron-positron annihilation.

Event display used for a public news "Paper on observation of Higgs boson decay to bottom quarks submitted!"

open access: yes, 2018

Radiative semileptonic decays of beautiful hadrons

open access: yesJournal of High Energy Physics
We derive predictions for the hadronic matrix elements of radiative semileptonic decays of beautiful hadrons within Heavy Quark Effective Theory (HQET), relevant for future measurements at Belle II and LHCb.

Partial next-to-next-to-leading-order corrections to the B → π form factors from light-cone sum rules

open access: yesJournal of High Energy Physics
By incorporating the available leading-power results at O α s $$ \mathcal{O}\left({\alpha}_s\right) $$ and next-to-leading-power corrections at tree level, we compute the O α s 2 β 0 $$ \mathcal{O}\left({\alpha}_s^2{\beta}_0\right) $$ contribution to the
