Berichte zur Wissenschaftsgeschichte, Volume 48, Issue 1-2, Page 143-162, August 2025.Abstract Short‐lived, unobservable, and not subject to the usual rules of conservation of energy and momentum, virtual particles—an integral part of the conceptual framework of quantum field theory (QFT)—exhibit a number of curious characteristics which, in recent decades, have in part fueled important discussions about their ontological status ...

B s → Kℓν ℓ and B (s) → π(K)ℓ + ℓ − decays at large recoil and CKM matrix elements
Journal of High Energy Physics, 2017 We provide hadronic input for the B-meson semileptonic transitions to a light pseudoscalar meson at large recoil. The B s → K form factor calculated from QCD light-cone sum rule is updated, to be used for a |V ub | determination from the B s → Kℓν width.

Partition Functions and Mass Action Constants of Plasmas of Light Elements at Higher Temperatures
Contributions to Plasma Physics, Volume 65, Issue 7, August 2025.ABSTRACT We first analyze the relations between the work of Planck and Klimontovich and show that Klimontovich's kinetic theory of non‐ideal plasmas confirms Planck's partition function for the hydrogen plasma. We discuss and check the Planck‐Brillouin‐Larkin (PBL) expressions for Hydrogen with PIMC calculations and derive new partition functions and ...

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.

Two Micron‐Size Dark Dimensions
Fortschritte der Physik, Volume 73, Issue 8, August 2025.Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.

The influence of Wilson lines on heavy quark anti-quark potential and mass
Journal of High Energy PhysicsThe holographic heavy quark potential is investigated via holographic Wilson loops in the AdS soliton with gauge potential. We analyze two types of holographic Wilson loops. In the first type, holographic heavy quark potential shows the area law behavior.

Heavy Flavour Working Group Summary
, 2012 We review theoretical and phenomenological aspects of heavy flavour production as discussed in the heavy flavour working group of the DIS 2012. Recent theoretical progress includes approximate NNLO calculations for heavy quark structure functions in deep

Heavy quark physics in the covariant quark model.
, 2014 I give a short introduction to the covariant quark model and its applications to heavy quark physics. The special emphasis will be devoted to the semileptonic, rare and radiative decays of the $\Lambda_b$-baryon.

Advanced Physics Research, Volume 4, Issue 7, July 2025.The paper discusses the role of scale anomaly in generating edge electric currents via the scale magnetic effect in scalar electrodynamics. Although the boundary electric current is much weaker than the Meissner current induced in superconducting materials, the scale anomaly can enhance conductivity near the boundary of the material.

Heavy-light meson spectrum with and without NRQCD
, 2000 Results for the spectrum of S and P-wave charmed mesons are obtained in the quenched approximation from a tadpole-improved anisotropic gauge field action and a D234 quark action.
