The pion in the graviton soft-wall model: phenomenological applications

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
The holographic graviton soft-wall model, introduced to describe the spectrum of scalar and tensor glueballs, is improved to incorporate the realization of chiral-symmetry as in QCD.

Pomerons and Lattices: a Progress Report [PDF]

open access: yes, 1996
We report on some attempts to use lattice QCD to investigate topics in strong interactions phenomenology which are usually interpreted in terms of soft Pomeron exchange.Comment: Talk presented at LAT96, 3 pages, Latex, one style file and 2 PostScript ...

Higher-twist B-meson distribution amplitudes in HQET

open access: yesJournal of High Energy Physics, 2017
We present a systematic study of higher-twist distribution amplitudes (DAs) of the B-meson which give rise to power-suppressed 1/m B contributions to B-decays in final states with energetic light particles in the framework of QCD factorization.

Two Micron‐Size Dark Dimensions

open access: yesFortschritte der Physik, Volume 73, Issue 8, August 2025.
Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.

Maximum Mass Limit of Generalized MIT Compact Star: A Theoretical Study of Thin Shell Dynamics and Gravitational Lensing

open access: yesFortschritte der Physik, Volume 73, Issue 8, August 2025.
Abstract In this study, the properties, equilibrium, and stability of compact objects within the framework of teleparallel gravity with the generalized MIT bag model are investigated. By incorporating the modified field equations, the influence of the generalized bag constant on the structure and physical characteristics of quark stars and neutron ...

Power corrections for N-jettiness subtractions at O α s $$ \mathcal{O}\left({\alpha}_s\right) $$

open access: yesJournal of High Energy Physics, 2018
We continue the study of power corrections for N -jettiness subtractions by analytically computing the complete next-to-leading power corrections at O α s $$ \mathcal{O}\left({\alpha}_s\right) $$ for colorsinglet production.

Visible GeV ALP from TeV Vector‐Like Leptons

open access: yesFortschritte der Physik, Volume 73, Issue 3, March 2025.
Abstract A model is presented where a GeV axion‐like‐particle (ALP) is predicted in a large portion of the parameter space due to the presence of explicit Peccei–Quinn (PQ) symmetry‐breaking terms in an exotic leptonic sector. The latter provides a solution to the muon g−2$g-2$ anomaly, within the framework of the Linear Seesaw neutrino mechanism.

J/ψ polarization in the CGC+NRQCD approach

open access: yesJournal of High Energy Physics, 2018
We compute the J/ψ polarization observables λ θ , λ ϕ , λ θϕ in a Color Glass Condensate (CGC) + nonrelativistic QCQ (NRQCD) formalism that includes contributions from both color singlet and color octet intermediate states.

Fiducial cross sections for the lepton-pair-plus-photon decay mode in Higgs production up to NNLO QCD

open access: yesJournal of High Energy Physics, 2022
The rare three-body decay of a Higgs boson to a lepton-antilepton pair and a photon is starting to become experimentally accessible at the LHC. We investigate how higher-order QCD corrections to the dominant gluon-fusion production process impact on the ...

QCD and SUSY-QCD corrections to the Three-Body Decay of the Charged Higgs Boson

open access: yes, 1999
The ${\cal O}(\alpha_s)$ QCD corrections to the three-body decay width of the charged Higgs $\Gamma$($H^+\to W^+b\bar{b}$) are discussed in the MSSM model. Our calculations indicate that the standard QCD corrections to the three-body decay mode raise the
