Heavy and light quarks in the instanton vacuum
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 ...

Abstract The production, attenuation, and absorption of secondary cosmic rays (SCR) are influenced by atmospheric parameters such as air pressure and temperature. To reliably correlate SCR flux measurements with atmospheric ionization driven by energetic particle precipitation, these dependencies must be quantified.

Two-loop integrals for CP-even heavy quarkonium production and decays: elliptic sectors
By employing the differential equations, we compute analytically the elliptic sectors of two-loop master integrals appearing in the NNLO QCD corrections to CP-even\ heavy quarkonium exclusive production and decays, which turns out to be the last and ...

SU(3) F analysis for beauty baryon decays
We perform a general SU(3)F analysis of b → c c ¯ s d $$ b\to c\overline{c}s(d) $$ decays of members of the beauty baryon antitriplet to a member of the light baryon octet and a singlet. Under several reasonable assumptions we found A Ξ b 0 → Λ S / A Ξ b

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

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

Subleading-power corrections to the radiative leptonic B → γℓν decay in QCD
Applying the method of light-cone sum rules with photon distribution amplitudes, we compute the subleading-power correction to the radiative leptonic B → γℓν decay from the twist-two hadronic photon contribution at next-to-leading order in QCD; and ...

ABSTRACT The physics of heavy‐ion collisions is one of the most exciting and challenging directions of science for the last four decades. On the theoretical side one deals with a non‐abelian field theory, while on the experimental side today's largest accelerators are needed to enable these studies.

K S 0 − K L 0 asymmetries and CP violation in charmed baryon decays into neutral kaons
We study the K S 0 − K L 0 asymmetries and CP violations in charm-baryon decays with neutral kaons in the final state. The K S 0 − K L 0 asymmetry can be used to search for two-body doubly Cabibbo-suppressed amplitudes of charm-baryon decays, with the ...

ABSTRACT Pain can impair exercise performance, but its influence on motor control, in particular the effect of robust experimental pain on the timecourse of corticomotor responses throughout prolonged, exhaustive cycling, remains unclear. We tested the hypothesis that an augmented experimental pain intervention applied to exercising and non‐exercising ...
