The time-dependent CP asymmetry in B 0 → K resγ → π+π− K s 0 γ $$ {K}_s^0\gamma $$ decays

Journal of High Energy Physics, 2019
The time-dependent CP asymmetry in B 0 → K resγ → π+π− K Sγ is sensitive to the photon polarisation in the quark level process b → sγ. While this polarisation is predominantly left-handed in the standard model, it could be modified by the existence of ...

Revisiting quark-hadron duality for heavy meson non-leptonic decays in two-dimensional QCD

Physics Letters B, 2022
We study lifetimes of heavy mesons in the 't Hooft model, a large-Nc theory of strong interaction in two-dimensional spacetime. Since this model is solvable, one can evaluate the total decay widths through hadronic amplitudes that are determined ...

Exercise hyperpnoea: Unravelling layers of regulation

The Journal of Physiology, EarlyView.
Abstract figure legend Intensity‐dependent changes in hypercapnic ventilatory response (HCVR) and feedforward gain (GEX) during exercise hyperpnoea below the respiratory compensation point (RCP). Participants (N = 20; 10 females) completed a 44 min step‐incremental cycling protocol in the moderate (below gas exchange threshold (GET)) and heavy ...

Charmed baryon weak decays with SU(3) flavor symmetry

Journal of High Energy Physics, 2017
We study the semileptonic and non-leptonic charmed baryon decays with SU(3) flavor symmetry, where the charmed baryons can be B c  = (Ξ c 0, Ξ c +, Λ c +), B c ′ = (Σ c (++,+,0), Ξ c ′ (+,0), Ω c 0), B cc  = (Ξ cc + +, Ξ cc +, Ω c +) or B cc  = Ω ccc + +.

Neuromuscular Fatigue and Perceived Fatigability in the Hours Following a High‐Intensity Endurance Running Depend on the Exercise Protocol

European Journal of Sport Science, Volume 26, Issue 8, August 2026.
ABSTRACT This study investigated neuromuscular fatigue and perceived fatigability across different high‐intensity endurance running protocols. Twelve males (mean ± SD; V˙O2max $\dot{\mathrm{V}}{\mathrm{O}}_{2\,\max }$: 52.2 ± 6.9 mL/kg/min) ran ∼8.0 km: (i) at the velocity associated to the respiratory compensation point (vRCP; 5 × 8 min bouts ‒ RUN100%

Endpoint relations for baryons

Journal of High Energy Physics, 2021
Following our earlier work we establish kinematic endpoint relations for baryon decays using the Wigner-Eckart theorem and apply them to 1 2 → 1 2 $$ \frac{1}{2}\to \frac{1}{2} $$ and 1 2 → 3 2 $$ \frac{1}{2}\to \frac{3}{2} $$ baryon transitions.

Heavy-quark thresholds in Higgs-boson physics [PDF]

Physical Review D, 1990
We perform a comprehensive study of the effects related to a heavy-quark threshold in the production and decay of a scalar or pseudoscalar Higgs particle. We study the QCD corrections to the decay mode into a quark-antiquark pair and also the mixing of a Higgs boson with quarkonium states, both below and above the open-flavor threshold, which can ...

Five Weeks of Sprint Interval Training Increase Absolute Power Output Within Severe‐Intensity Domain Without Altering Muscle Activation or Fatigability

European Journal of Sport Science, Volume 26, Issue 7, July 2026.
ABSTRACT The study aimed to investigate whether a 5‐week sprint interval training (SIT) could improve neuromuscular function (NMF), alter electromyographic activity (EMG), and attenuate fatigability, ultimately resulting in improved cycling performance during constant work rate (CWR) exercise within the severe‐intensity domain.

Semileptonic $$s\rightarrow u$$ s → u decays of singly heavy baryons

European Physical Journal C: Particles and Fields
$$s\rightarrow u$$ s → u weak decays of heavy flavor hadrons play a unique role in the field of heavy flavor physics. In this work, we investigate semileptonic $$s\rightarrow u$$ s → u decays of singly heavy baryons in the light-front approach under the ...

Parity doubling as a tool for right-handed current searches

Journal of High Energy Physics, 2018
The V-A structure of the weak interactions leads to definite amplitude hierarchies in exclusive heavy-to-light decays mediated by b → (d, s)γ and b→d,sℓℓ¯ $$ b\to \left(d,\ s\right)\ell \overline{\ell} $$. However, the extraction of right-handed currents
