Pentagon integrals to arbitrary order in the dimensional regulator
Journal of High Energy Physics, 2021 We analytically calculate one-loop five-point Master Integrals, pentagon integrals, with up to one off-shell leg to arbitrary order in the dimensional regulator in d = 4−2𝜖 space-time dimensions.

Higher-twist B-meson distribution amplitudes in HQET
Journal of High Energy Physics, 2017 We present a systematic study of higher-twist distribution amplitudes (DAs) of the B-meson which give rise to power-suppressed 1/m B contributions to B-decays in final states with energetic light particles in the framework of QCD factorization.

QCD phenomenology in tachyon condensation theory [PDF]
, 2021 This thesis is intended to contribute to the long standing problems associated with theoretical QCD theory. We aim at touching on all possible QCD features such as; color confinement, asymptotic freedom and chiral symmetry breaking.

Multimodal Fragmentation of Hidden‐Heavy Scalar Tetraquarks With HF‐NRevo
Annalen der Physik, Volume 538, Issue 10, October 2026.A state‐driven multimodal framework is introduced for hidden‐heavy scalar tetraquark fragmentation. Distinct microscopic production mechanisms are consistently related to different internal hadronic configurations while theoretical uncertainties are systematically quantified.

Generalized Beth–Uhlenbeck Entropy Formula From the Φ‐Derivable Approach
Contributions to Plasma Physics, Volume 66, Issue 7-8, September 2026.ABSTRACT We derive a generalized Beth–Uhlenbeck formula for the entropy of a dense fermion system with strong two‐particle correlations, including scattering states and bound states. We work within the Φ‐derivable approach to the thermodynamic potential.

Signals of the QCD Phase Transition in the Heavens [PDF]
, 2007 The modern phase diagram of strongly interacting matter reveals a rich structure at high-densities due to phase transitions related to the chiral symmetry of quantum chromodynamics (QCD) and the phenomenon of color superconductivity.

QED factorization of two-body non-leptonic and semi-leptonic B to charm decays
Journal of High Energy Physics, 2021 The QCD×QED factorization is studied for two-body non-leptonic and semi-leptonic B decays with heavy-light final states. These non-leptonic decays, like B ¯ s 0 → D s + π − $$ {\overline{B}}_{(s)}^0\to {D}_{(s)}^{+}{\pi}^{-} $$ and B ¯ d 0 → D + K − $$ {\

The DNA of Calabi–Yau Hypersurfaces
Fortschritte der Physik, Volume 74, Issue 2, February 2026.Abstract Genetic Algorithms are implemented for triangulations of four‐dimensional reflexive polytopes, which induce Calabi–Yau threefold hypersurfaces via Batyrev's construction. These algorithms are shown to efficiently optimize physical observables such as axion decay constants or axion–photon couplings in string theory compactifications.
