Published in 2017 at "Journal of High Energy Physics"

DOI: 10.1007/jhep07(2018)035

Abstract: A bstractUsing the background-field method we demonstrate the Becchi-Rouet-Stora-Tyutin (BRST) structure of counterterms in a broad class of gauge theories. Put simply, we show that gauge invariance is preserved by renormalization in local gauge field… read more here.

Published in 2018 at "Magnetic resonance imaging"

DOI: 10.1016/j.mri.2018.06.006

Abstract: PURPOSE We developed a non-regularized, variable kernel, sophisticated harmonic artifact reduction for phase data (NR-VSHARP) method to accurately estimate local tissue fields without regularization for quantitative susceptibility mapping (QSM). We then used a digital brain… read more here.

Published in 2022 at "Physical Review D"

DOI: 10.1103/physrevd.107.074016

Abstract: We compute dijet production in Deep Inelastic Scattering at low $x$ in the dipole formalism at next-to-eikonal accuracy. We calculate the contributions induced by single photon exchange of either longitudinal or transverse polarization. We include… read more here.

Published in 2022 at "Zeitschrift fur medizinische Physik"

DOI: 10.48550/arxiv.2204.02760

Abstract: INTRODUCTION Background field removal (BFR) is a critical step required for successful quantitative susceptibility mapping (QSM). However, eliminating the background field in brains containing significant susceptibility sources, such as intracranial hemorrhages, is challenging due to… read more here.
