Classical gluon production amplitude in heavy-ion collisions

open access: yesEPJ Web of Conferences, 2016
The initial condition for the formation of the Quark-Gluon Plasma, the distribution of quarks and gluons produced in the initial stages of nuclear collisions, is the fundamental building block of heavy-ion theory.

The static hard-loop gluon propagator to all orders in anisotropy

open access: yesJournal of High Energy Physics, 2017
We calculate the (semi-)static hard-loop self-energy and propagator using the Keldysh formalism in a momentum-space anisotropic quark-gluon plasma. The static retarded, advanced, and Feynman (symmetric) self-energies and propagators are calculated to all

LHCb Overview [PDF]

open access: yesEPJ Web of Conferences
The LHCb experiment has a complete heavy ion physics program, including studies of pp, pA, AA, and UPC events delivered by the Large Hadron Collider, along with a rapidly expanding fixed-target capability. With unique acceptance and detector capabilities,

|Vub| determination and testing of lepton flavour universality in semileptonic Bc → D(∗) decays

open access: yesJournal of High Energy Physics, 2020
In light of prospects for measurements of B c  → D (∗) lv decays in the upcoming Upgrade II of the LHC, we show that by using calculated B c  → D (∗) form factors a competitive extraction of the |V ub | CKM matrix element from the B c → Dμ v ¯ μ $$ {B}_c\

Charged and neutral B ¯ u , d , s $$ {\overline{B}}_{u,d,s} $$ → γ form factors from light cone sum rules at NLO

open access: yesJournal of High Energy Physics, 2021
We present the first analytic O α s $$ \mathcal{O}\left({\alpha}_s\right) $$ -computation at twist-1,2 of the B ¯ u , d , s $$ {\overline{B}}_{u,d,s} $$ → γ form factors within the framework of sum rules on the light-cone. These form factors describe the

Towards B ¯ → X s γ $$ \overline{B}\to {X}_s\gamma $$ at the NNLO in QCD without interpolation in m c

open access: yesJournal of High Energy Physics, 2020
Strengthening constraints on new physics from the B ¯ → X s γ $$ \overline{B}\to {X}_s\gamma $$ branching ratio requires improving accuracy in the measurements and the Standard Model predictions.
