Probing top quark neutral couplings in the Standard Model Effective Field Theory at NLO in QCD [PDF]

, 2016
A bstractTop quark pair production in association with a Z-boson or a photon at the LHC directly probes neutral top-quark couplings. We present predictions for these two processes in the Standard Model (SM) Effective Field Theory (EFT) at next-to-leading

Freeze-in Dirac neutrinogenesis: thermal leptonic CP asymmetry

European Physical Journal C: Particles and Fields, 2020
We present a freeze-in realization of the Dirac neutrinogenesis in which the decaying particle that generates the lepton-number asymmetry is in thermal equilibrium.

Jet tomography in high-energy nuclear collisions [PDF]

EPJ Web of Conferences, 2019
When an energetic parton traversing the QCD medium, it may suffer multiple scatterings and lose energy. This jet quenching phenomenon may lead to the suppression of leading hadron productions as well as medium modifications of full jet observables in ...

Non-perturbative structure of the polarized nucleon sea

, 2003
We investigate the flavour and quark-antiquark structure of the polarized nucleon by calculating the parton distribution functions of the nucleon sea using the meson cloud model. We find that the SU(2) flavor symmetry in the light antiquark sea and quark-

Exercise limitations in amyloid cardiomyopathy assessed by cardiopulmonary exercise testing—A multicentre study

ESC Heart Failure, Volume 12, Issue 2, Page 1326-1335, April 2025.
Abstract Aims Amyloid cardiomyopathy is caused by the deposition of light chain (AL) or transthyretin amyloid (ATTR) fibrils, that leads to a restrictive cardiomyopathy, often resulting in heart failure (HF) with preserved or reduced ejection fraction.

The $$\varvec{\Lambda _b\rightarrow \Lambda (\rightarrow p\pi ^-)\mu ^+\mu ^-}$$ Λ b → Λ ( → p π - ) μ + μ - decay in the aligned two-Higgs-doublet model

European Physical Journal C: Particles and Fields, 2017
The rare baryonic decay $$\Lambda _b\rightarrow \Lambda (\rightarrow p\pi ^-)\mu ^+\mu ^-$$ Λ b → Λ ( → p π - ) μ + μ - provides valuable complementary information compared to the corresponding mesonic $$b\rightarrow s\mu ^+\mu ^-$$ b → s μ + μ ...

Delta and Omega electromagnetic form factors in a Dyson-Schwinger/Bethe-Salpeter approach

, 2010
We investigate the electromagnetic form factors of the Delta and the Omega baryons within the Poincare-covariant framework of Dyson-Schwinger and Bethe-Salpeter equations.

Determination of the quark coupling strength |Vub| using baryonic decays [PDF]

Nature Physics, 2015
In the Standard Model of particle physics, the strength of the couplings of the b quark to the u and c quarks, |Vub| and |Vcb|, are governed by the coupling of the quarks to the Higgs boson.
