Combined explanations of B-physics anomalies, $$(g-2)_{e, \mu }$$ ( g - 2 ) e , μ and neutrino masses by scalar leptoquarks

European Physical Journal C: Particles and Fields, 2022
We extend the contents of the standard model (SM) by introducing TeV-scale scalar leptoquarks to generate neutrino masses and explain some current observed deviations from the SM predictions, including the anomalous magnetic moments of charged leptons ...

Impact of living and training at low altitude for several years on endurance performance at higher altitude: Myth or reality

Experimental Physiology, EarlyView.
Abstract The physiological adaptations of long‐term high‐altitude residents without high‐altitude genetic ancestry remain poorly characterized. This study investigated whether permanent residence at low altitude (1200 m) influences performance at higher altitude (2500 m). We compared exercise responses at 2500 m in endurance‐trained athletes living for

$${b\rightarrow c\tau \nu }$$ b→cτν transitions in the standard model effective field theory

European Physical Journal C: Particles and Fields, 2019
The $$R(D^{(*)})$$ R(D(∗)) anomalies observed in $$B\rightarrow D^{(*)}\tau \nu $$ B→D(∗)τν decays have attracted much attention in recent years. In this paper, we study the $$B\rightarrow D^{(*)}\tau \nu $$ B→D(∗)τν , $$\Lambda _b\rightarrow \Lambda _c ...

The acute effects of exercise intensity and inorganic nitrate supplementation on the Buckberg ratio in postmenopausal females

Experimental Physiology, EarlyView.
Abstract Menopause increases coronary heart disease risk, in part through reduced oestrogen‐mediated nitric oxide (NO) bioavailability. The Buckberg ratio, an index of myocardial oxygen supply–demand balance, in which higher values reflect more favourable myocardial perfusion, is lower in postmenopausal females (PMFs) than in age‐matched males.

Evaluation of the two lightest quark masses

Ядерна фізика та енергетика, 2017
Simple relations between the masses of the two lightest up and down quarks were obtained on the basis of the simple physically based model compatible with the present-day theory of strong interactions, i.e. with quantum chromodynamics.

Extracting jet transport coefficient via single hadron and dihadron productions in high-energy heavy-ion collisions

European Physical Journal C: Particles and Fields, 2019
We study the suppressions of high transverse momentum single hadron and dihadron productions in high-energy heavy-ion collisions based on the framework of a next-to-leading-order perturbative QCD parton model combined with the higher-twist energy loss ...

Arterial–venous differences of brain‐derived neurotrophic factor isoforms across the brain and muscle after exercise at different intensities

The Journal of Physiology, EarlyView.
Abstract figure legend Exercise‐induced increases in forearm venous plasma and serum brain‐derived neurotrophic factor (BDNF) are often assumed to be indicative of release from the brain. Sixteen healthy and physically fit adults (20–40 years old) were recruited to investigate whether exercise‐induced changes in forearm venous mature BDNF (mBDNF) and ...

Quark and Gluon Form Factors at Three Loops in Perturbative QCD [PDF]

, 2009
We compute the quark and gluon form factors at up to three-loop order within massless perturbative Quantum Chromodynamics by studying the photon-quark-anti-quark vertex and the effective vertex of a Higgs boson and two gluons.

Mass splitting and spin alignment for $$\phi $$ ϕ mesons in a magnetic field in NJL model

European Physical Journal C: Particles and Fields
Based on the Nambu–Jona–Lasinio (NJL) model, we develop a framework for calculating the spin alignment of vector mesons and applied it to study $$\phi $$ ϕ mesons in a magnetic field.

RD*,RK* $$ {R}_{D^{\left(*\right)}},{R}_{K^{\left(*\right)}} $$ and neutrino mass in the 2HDM-III with right-handed neutrinos

Journal of High Energy Physics, 2018
Given that the two-Higgs-doublet model of type III (2HDM-III) has the potential to address the RD* $$ {R}_{D^{\left(*\right)}} $$ anomalies while the resolution to the RK* $$ {R}_{K^{\left(*\right)}} $$ deficits requires new degrees of freedom within ...
