The high-energy limit of perturbative QCD: Theory and phenomenology [PDF]
EPJ Web of Conferences, 2022 After a brief introduction of formal and phenomenological progresses in the study of the high-energy limit of perturbative QCD, we present arguments supporting the statement that the inclusive emission of Higgs bosons or heavy-flavored hadrons acts as ...

Precision QCD phenomenology of exotic spin-2 search at the LHC [PDF]
Journal of High Energy Physics, 2020 The complete next-to-next-to leading order (NNLO) QCD correction matched with next-to-next-to leading logarithm (NNLL) has been studied for Drell-Yan production via spin-2 particle at the Large hadron collider (LHC).

Extending the application of the light-cone sum rules method to low momenta using QCD renormalization-group summation: Theory and phenomenology [PDF]
Physical Review D, 2021 We show that using renormalization-group summation to generate the QCD radiative corrections to the π − γ transition form factor, calculated with lightcone sum rules (LCSR), renders the strong coupling free of Landau singularities while preserving the ...

The B ¯ → π form factors from QCD and their impact on |V ub |. [PDF]
J High Energy Phys, 2021 We revisit light-cone sum rules with pion distribution amplitudes to determine the full set of local B ¯ $$ \overline{B} $$ → π form factors. To this end, we determine all duality threshold parameters from a Bayesian fit for the first time.

Phenomenology of the companion-axion model: photon couplings
European Physical Journal C: Particles and Fields, 2022 We study the phenomenology of the ‘companion-axion model’ consisting of two coupled QCD axions. The second axion is required to rescue the Peccei–Quinn solution to the strong-CP problem from the effects of colored gravitational instantons. We investigate

Ising-QCD phenomenology close to the critical point [PDF]
Journal of Physics G: Nuclear and Particle Physics, 2018 We employ the recently introduced Ising-QCD partition function (N.~G. Antoniou {\it et al.}, Phys. Rev. D 97, 034015 (2018)) to explore in detail the behaviour of the moments of the baryon-number, within the critical region around the critical endpoint ...

Quark flavor phenomenology of the QCD axion [PDF]
, 2020 Axion models with generation-dependent Peccei-Quinn charges can lead to flavor-changing neutral currents, thus motivating QCD axion searches at precision flavor experiments.

The Low‐Scale Seesaw Solution to the MW$M_W$ and (g−2)μ$(g-2)_\umu$ Anomalies
Fortschritte der Physik, Volume 71, Issue 4-5, May 2023., 2023 Abstract The recent CDF‐II measurement of the W‐boson mass shows a strong tension with the corresponding Standard Model prediction. Once active neutrino masses are explained in the context of the Low‐Scale Seesaw mechanisms, this tension can be resolved.

Inclusive production of heavy quarkonia in pNRQCD
Journal of High Energy Physics, 2021 We develop a formalism for computing inclusive production cross sections of heavy quarkonia based on the nonrelativistic QCD and the potential nonrelativistic QCD effective field theories.

QCD traveling waves phenomenology revisited [PDF]
, 2020 In this paper, we review and update the Amaral-Gay Ducati-Betemps-Soyez saturation model, by testing it against the recent H1-ZEUS combined data on deep inelastic scattering, including heavy quarks in the dipole amplitude.
