The decomposition of neutron-antineutron oscillation operators

Journal of High Energy Physics, 2023
We study the systematic decomposition of the dimension nine neutron-antineutron oscillation operators at tree and one-loop levels. We discuss the topologies’ generation and the assignment of the chiral quarks.

On the strange quark mass with improved staggered quarks [PDF]

, 2002
We present results on the sum of the masses of light and strange quark using improved staggered quarks. Our calculation uses 2+1 flavours of dynamical quarks. The effects of the dynamical quarks are clearly visible.

Setting sail for Paris 2024: Retrospective analysis of world‐class ILCA 7 Olympic sailors’ cardiorespiratory fitness (2015–2020)

Experimental Physiology, EarlyView.
Abstract The aim of this retrospective analysis was to provide a more comprehensive understanding of the cardiorespiratory profile of world‐class ILCA‐7 sailors (n = 3, all males), through a longitudinal evaluation offering real‐world data on physiological profile and exercise intensity domains. The cardiopulmonary exercise testing (CPET) was performed

Impact of a 12‐week high‐intensity interval training intervention on cardiac structure and function after COVID‐19 at 12‐month follow‐up

Experimental Physiology, EarlyView.
Abstract In patients previously hospitalised for COVID‐19, a 12‐week high‐intensity interval training (HIIT) intervention has previously been shown to increase left ventricular mass (LVM) immediately after the intervention. In the present study, we examined the effects of the same HIIT scheme on LVM, pulmonary diffusing capacity, symptom severity and ...

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.

Decay mechanism of quarks and leptons [PDF]

arXiv, 2005
The top-family quarks will decay in charm-family quarks while beauty-family quarks serve the purpose of spectrators. Decay matrix is suggested for quark and lepton decays.

Impact of exercise training on tumour‐infiltrating T cells in human prostate cancer: A secondary analysis of a randomized controlled trial (PRO‐TEST)

Experimental Physiology, EarlyView.
Abstract Exercise training reduces tumour growth by increasing tumour‐infiltrating T‐cell density in preclinical models. However, it remains unknown whether exercise training can modify intratumoural T cells in humans.The aim of this study was to compare the effects of an exercise training intervention versus control on human prostate intratumoural T ...

Heavy-light quarks interactions in QCD vacuum [PDF]

arXiv, 2014
QCD vacuum instantons induce very strong interactions between light quarks, which generate large dynamical light quark mass M for initially almost massless quarks and can bound these quarks to produce almost massless pions in accordance with the spontaneous breaking of chiral symmetry (S\chiSB).

Combined effects of normobaric hypoxia and cold on respiratory system responses to high‐intensity exercise

Experimental Physiology, EarlyView.
Abstract Cold temperatures (<−15°C) increase exercise‐induced bronchoconstriction (EIB), while hypoxic‐induced hyperventilation exacerbates respiratory muscle fatigue for a given exercising task. This study aimed to determine the individual and combined effects of cold and normobaric hypoxia on the respiratory system responses to high‐intensity ...

Deciphering the Belle II data on B → Kν ν ¯ $$ B\to K\nu \overline{\nu} $$ decay in the (dark) SMEFT with minimal flavour violation

Journal of High Energy Physics
Recently, the Belle II collaboration announced the first measurement of the branching ratio B B + → K + ν ν ¯ $$ \mathcal{B}\left({B}^{+}\to {K}^{+}\nu \overline{\nu}\right) $$ , which is found to be about 2.7σ higher than the Standard Model (SM ...
