Inclusive production of heavy quarkonia in pNRQCD
Journal of High Energy Physics, 2021 We develop a formalism for computing inclusive production cross sections of heavy quarkonia based on the nonrelativistic QCD and the potential nonrelativistic QCD effective field theories.

Transverse momentum dependent parton densities in a proton from the generalized DAS approach
Journal of High Energy Physics, 2020 We use the Bessel-inspired behavior of parton densities at small Bjorken x values, obtained in the case of the flat initial conditions for DGLAP evolution equations in the double scaling QCD approximation (DAS), to evaluate the transverse momentum ...

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 = 4â2đ space-time dimensions.

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.

Recent progress on QCD inputs for axion phenomenology [PDF]
, 2017 The properties of the QCD axion are strictly related to the dependence of strong interactions on the topological parameter theta. We present a determination of the topological properties of QCD for temperatures up to around 600 MeV, obtained by lattice ...

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.

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

Non-leptonic B-decays in and beyond QCD factorisation [PDF]
, 2005 This thesis examines the non-leptonic B-decays within QCD factorization and beyond, to challenge the assumptions and limitations of the method. We analyse the treatment of the distribution amplitudes of light mesons and present a new model described by ...

An Overview of Scale Invariance in Proton Structure With Holographic Insights
Advances in High Energy Physics, Volume 2026, Issue 1, 2026.The concept of selfâsimilarity in the internal structure of the proton, rooted in scale invariance and fractal geometry, provides an intriguing framework for understanding the behavior of parton distribution functions (PDFs), particularly in the small x region probed in deep inelastic scattering (DIS).
