Jet Quenching in Non-Conformal Holography

, 2011
We use our non-conformal holographic bottom-up model for QCD described in 1012.0116 to further study the effect of the QCD trace anomaly on the energy loss of both light and heavy quarks in a strongly coupled plasma.

Exploring Dark Photon Production and Kinetic Mixing Constraints in Heavy‐Ion Collisions

Astronomische Nachrichten, Volume 346, Issue 3-4, March-May 2025.
ABSTRACT Vector U‐bosons, often referred to as “dark photons,” are potential candidates for mediating dark matter interactions. In this study, we outline a procedure to derive theoretical constraints on the upper bound of the kinetic mixing parameter ϵ2MU$$ {\upvarepsilon}^2\left({M}_U\right) $$ using dilepton data from heavy‐ion from SIS to RHIC ...

Higher twist corrections to doubly-charmed baryonic B decays

Journal of High Energy Physics
Baryonic two-body B mesons decays have been measured experimentally for some time, which provides an excellent ground for studying the QCD of baryonic B decays.

QED in B ¯ $$ \overline{B} $$ → K ¯ $$ \overline{K} $$ ℓ + ℓ − LFU ratios: theory versus experiment, a Monte Carlo study

Journal of High Energy Physics, 2022
Using analytic results obtained in a meson effective theory, that includes all infrared sensitive logs, we build a dedicated Monte Carlo framework to describe QED corrections in B ¯ $$ \overline{B} $$ → K ¯ $$ \overline{K} $$ ℓ + ℓ − for a generic form ...

Same-Sign Dilepton Excesses and Vector-like Quarks

, 2015
Multiple analyses from ATLAS and CMS collaborations, including searches for ttH production, supersymmetric particles and vector-like quarks, observed excesses in the same-sign dilepton channel containing b-jets and missing transverse energy in the LHC ...

Spatially Explicit Model to Disentangle Effects of Environment on Annual Fish Reproduction

Environmetrics, Volume 36, Issue 2, March 2025.
ABSTRACT Population growth models are essential tools for natural resources management and conservation since they provide understanding on factors affecting renewal of natural animal populations. However, we still do not properly understand how the processes underlying reproduction of natural animal populations are affected by the environment at the ...

Visible GeV ALP from TeV Vector‐Like Leptons

Fortschritte 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.

Purpose and Providence in Evolutionary Perspective: Considerations for Theological Anthropology in Light of Biocultural Evolution and Genetic Engineering

The Heythrop Journal, Volume 66, Issue 2, Page 157-173, March 2025.
Abstract We argue here that bringing insights from evolution and bioengineering to bear on traditional accounts of divine providence helps to illustrate just how complex providence is and how difficult it is to achieve. While other non‐human animals might exhibit greater agency in creation and its evolutionary development than has traditionally been ...

Quark ACM with topologically generated gluon mass

, 2016
We investigate the effect of a small, gauge-invariant mass of the gluon on the anomalous chromomagnetic moment of quarks (ACM) by perturbative calculations at one loop level.

B ¯ → D ¯ D $$ \overline{B}\to \overline{D}D $$ decays and the extraction of f d /f u at hadron colliders

Journal of High Energy Physics
We perform a detailed model-independent phenomenological analysis of B ¯ → D ¯ D $$ \overline{B}\to \overline{D}D $$ decays. Employing an SU(3) F analysis including symmetry-breaking contributions together with a conservative power counting for various ...
