Journal Article Mathematics · March 1, 2025 In this work, we analyze the vanishing cycles of Feynman loop integrals by the means of the Mayer–Vietoris spectral sequence. A complete classification of possible vanishing geometries is obtained. We use this result for establishing an asymptotic expansio ... Full text Cite

Exact and leading order radiative effects in semi-inclusive deep inelastic scattering

Journal Article Physical Review D · April 1, 2024 Radiative effects in semi-inclusive hadron leptoproduction of unpolarized particles are calculated within the leading order approximation. The contributions of the infrared-free sum of the effects of real and virtual photon emission as well as the contribu ... Full text Cite

Lowest-order QED radiative corrections in unpolarized elastic electron–deuteron scattering beyond the ultra-relativistic limit for the proposed deuteron charge radius measurement at Jefferson laboratory

Journal Article European Physical Journal A · November 1, 2023 Analogous to the well-known proton charge radius puzzle, a similar puzzle exists for the deuteron charge radius, rd . There are discrepancies observed in the results of rd , measured from electron-deuteron (e- d) scattering experiment ... Full text Cite

Complete lowest order radiative corrections in semi-inclusive scattering of polarized particles

Journal Article European Physical Journal A · October 1, 2023 The lowest order radiative corrections to the cross section and asymmetries measured in experiments on semi-inclusive deep inelastic scattering of polarized particles were calculated. Both exact and leading log expressions were presented and discussed for ... Full text Cite

SIDIS-RC EvGen: A Monte-Carlo event generator of semi-inclusive deep inelastic scattering with the lowest-order QED radiative corrections

Journal Article Computer Physics Communications · June 1, 2023 SIDIS-RC EvGen is a C++ standalone Monte-Carlo event generator for studies of semi-inclusive deep inelastic scattering (SIDIS) processes at medium to high lepton beam energies. In particular, the generator contains binary and library components for generat ... Full text Cite

Perturbation theory in (2,2) signature

Journal Article Physical Review D Particles Fields Gravitation and Cosmology · May 20, 2013 We identify a natural analytic continuation in four dimensions from Minkowski signature to a signature with two timelike momentum components. For two-, three-, and four-point diagrams whose external momenta define a scattering plane, this continuation can ... Full text Cite

Non-perturbative computation of double inclusive gluon production in the Glasma

Journal Article Journal of High Energy Physics · January 1, 2010 The near-side ridge observed in A+A collisions at RHIC has been described as arising from the radial flow of Glasma flux tubes formed at very early times in the collisions. We investigate the viability of this scenario by performing a non-perturbative nume ... Full text Cite
