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 ...

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 ...

Sex differences in the prefrontal cortex and muscle oxygenation during exercise until exhaustion in endurance‐trained individuals

Experimental Physiology, EarlyView.
Abstract figure legend During cardiopulmonary exercise testing, the decline in oxygenation in the prefrontal cortex of women is striking. This crucial brain area is directly involved in planning motor tasks. The decline is particularly pronounced at higher exercise intensities, especially after reaching the respiratory compensation point or anaerobic ...

Phenomenological anatomy of top-quark FCNCs induced by a light scalar singlet

Journal of High Energy Physics
Scalar singlets under the Standard Model gauge group appear naturally in many well-motivated New Physics scenarios, such as the composite Higgs models. Unlike the Higgs boson in the Standard Model, they can induce large flavour-changing neutral currents (

B s(d) − B ¯ $$ \overline{B} $$ s(d) mixing and B s → μ + μ − decay in the NMSSM with the Flavour Expansion Theorem

Journal of High Energy Physics, 2019
In this paper, motivated by the observation that the Standard Model predictions are now above the experimental data for the mass difference ΔM s(d), we perform a detailed study of B s(d) − B ¯ $$ \overline{B} $$ s(d) mixing and B s → μ + μ − decay in the

The global geometrical property of jet events in high-energy nuclear collisions

European Physical Journal C: Particles and Fields, 2020
We present the first theoretical study of medium modifications of the global geometrical pattern, i.e., transverse sphericity ( $$S_{\perp }$$ S ⊥ ) distribution of jet events with parton energy loss in relativistic heavy-ion collisions.

Light Quark Spin-Flavor Symmetry for Baryons Containing a Heavy Quark in Large N QCD

, 1993
The couplings and interactions of baryons containing a heavy quark are related by light quark spin-flavor symmetry in the large $N$ limit. The single pion coupling constant which determines all heavy quark baryon-pion couplings is equal to the pion ...

Effect of hypoxia on muscle activation at equivalent absolute and relative intensity during incremental and constant load exercise to task failure

Experimental Physiology, EarlyView.
Abstract We examined the impact of moderate hypoxia (HYPO) on muscle activation during incremental exercise matched for both absolute and equivalent relative intensity. Fifteen active subjects (10 males, 5 females) completed two ramp incremental test and two step tests in normoxia (NORM; FiO2${F_{{\mathrm{i}}{{\mathrm{O}}_2}}}$ = 0.209) and HYPO (FiO2${
