Decoupling of heavy quarks at four loops and effective Higgs-fermion coupling

open access: yesPhysics Letters B, 2015
We compute the decoupling constant ζm relating light quark masses of effective nl-flavour QCD to (nl+1)-flavour QCD to four-loop order. Immediate applications are the evaluation of the MS¯ charm quark mass with five active flavours and the bottom quark ...

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.

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

open access: yesThe 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 ...

Energy loss of heavy quarks in the isotropic collisional hot QCD medium

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
The collisional energy loss of heavy partons (charm and bottom quarks) has been determined within the framework of semi-classical transport theory implying the Bhatnagar–Gross–Krook (BGK) collisional kernel.

Analytic decay width of the Higgs boson to massive bottom quarks at order α s 3 $$ {\alpha}_s^3 $$

open access: yesJournal of High Energy Physics
The Higgs boson decay into bottom quarks is the dominant decay channel contributing to its total decay width, which can be used to measure the bottom quark Yukawa coupling and mass.

Search for heavy resonances decaying to a top quark and a bottom quark in the lepton+jets final state in proton–proton collisions at 13 TeV

open access: yesPhysics Letters B, 2018
A search is presented for narrow heavy resonances decaying to a top quark and a bottom quark using data collected by the CMS experiment at s=13TeV in 2016. The data set analyzed corresponds to an integrated luminosity of 35.9fb−1 .

Study of the spectra and decay widths of singly heavy baryons [PDF]

open access: yesEPJ Web of Conferences
We present a study of the spectra and strong decay widths of singly heavy baryons. The masses of singly heavy baryons up to the D-wave are calculated within a constituent quark model, employing the three-quark and quarkdiquark schemes.
