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 ...

Symmetries of Doubly Heavy Baryons
, 2012 For very heavy quarks, the two heavy quarks in a doubly heavy baryon are expected to form a pointlike, heavy diquark in an antitriplet color configuration.

Overview of Charm Physics at RHIC [PDF]
, 2006 Heavy-quark production provides a sensitive probe of the gluon structure of nucleons and its modication in nuclei. It is also a key probe of the hot-dense matter created in heavy-ion collisions.

Experimental Physiology, Volume 111, Issue 4, Page 1919-1932, 1 April 2026.Abstract Kenyan athletes have dominated competitive middle‐ and long‐distance running for more than half a century, a phenomenon suggested to be attributable, at least in part, to superior running economy. Given that lower‐leg anthropometry is an important determinant of running economy, a key contributor to the athletic performance of Kenyan runners ...

Heavy and light quarks in the instanton vacuum
, 2011 Assuming the gluon field is well approximated by instanton configurations we derive a light quarks determinant and calculate its contribution to the specific heavy quarks correlators -- namely, the heavy quark propagator and heavy quark-aniquark ...

Cardiopulmonary function in special operations forces compared to conventional infantry soldiers
Experimental Physiology, Volume 111, Issue 4, Page 1626-1635, 1 April 2026.Abstract Fitness is essential to military personnel in general, especially in the special operations forces (SOF), where the demanding tasks require a high level of physical fitness and mental robustness. However, little research has been done on SOF to characterise the putative underlying cardiopulmonary adaptations that distinguish them from ...

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 + +.

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.

Experimental Physiology, Volume 111, Issue 4, Page 1988-2001, 1 April 2026.Abstract Ski mountaineering (SkiMo) is a new Olympic sport with extreme endurance demands and altitude exposure. Previous studies have focused on traditional cardiorespiratory variables, such as maximal oxygen consumption (V̇O2max${\dot V_{{{\mathrm{O}}_{\mathrm{2}}}{\mathrm{max}}}}$) or ventilatory thresholds, but, to our knowledge, did not report ...
