Master Integrals for the two-loop, non-planar QCD corrections to top-quark pair production in the quark-annihilation channel

Journal of High Energy Physics, 2019
We present the analytic calculation of the Master Integrals for the twoloop, non-planar topologies that enter the calculation of the amplitude for top-quark pair hadroproduction in the quark-annihilation channel.

Recommended but Not High Carbohydrate Dose Improves Performance After Heavy‐ but Not Moderate‐Intensity Exercise in Recreationally Trained Participants

Scandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 5, May 2026.
ABSTRACT This study determined: (i) whether carbohydrates (CHO) supplementation had beneficial effects on endurance performance, as assessed by a time trial (TT) test, following exercise bouts within either the moderate‐ or heavy‐intensity exercise; and (ii) if above the recommended dose of CHO supplementation would impact endurance performance.

Neural network modeling of heavy-quark potential from holography

European Physical Journal C: Particles and Fields
Using Multi-Layer Perceptrons (MLP) and Kolmogorov–Arnold Networks (KAN), we construct a holographic model based on lattice QCD data for the heavy-quark potential in the 2+1 system.

Experimental Highlights: Heavy Quark Physics in Heavy-Ion Collisions at RHIC

EPJ Web of Conferences, 2017
The discovery at RHIC of large high-pT suppression and flow of electrons from heavy quarks flavors have altered our view of the hot and dense matter formed in central Au + Au collisions at √sNN = 200 GeV.

Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

Fortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Running economy and lower‐limb anthropometry in adult male Kenyan and Danish middle‐ and long‐distance runners and in untrained adolescents

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 ...

Coulomb artifacts and breakdown of perturbative matching in lattice NRQCD

Journal of High Energy Physics, 2017
By studying an explicit analytical solution of the Schrödinger equation with the Coulomb potential on the lattice we demonstrate a breakdown of perturbative matching for the description of the Coulomb artifacts in lattice NRQCD, which leads to a large ...

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 ...

A method for model-independent measurement of the CKM angle β via time-dependent analysis of the B 0 → Dπ + π −, D → K s 0 π + π − decays

Journal of High Energy Physics, 2018
A new method for model-independent measurement of the CKM angle β is proposed, that employs time-dependent analysis of flavour-tagged B 0 → Dπ+π− decays with D meson decays into C P $$ \mathcal{C}\mathcal{P} $$ -specific and K s 0 π + π − final states ...

Sex and performance‐level differences in aerobic and haematological parameters among elite ski mountaineering athletes

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 ...
