Journal of High Energy Physics, 2021 We study the fragmentation function of the gluon to color-octet 3 S 1 heavy quark-antiquark pair using the soft gluon factorization (SGF) approach, which expresses the fragmentation function in a form of perturbative short-distance hard part convoluted ...

Tevatron Run-1 Z Boson Data and Collins-Soper-Sterman Resummation Formalism [PDF]
, 2002 We examine the effect of the Z-boson transverse momentum distribution measured at the Run-1 of the Tevatron on the nonperturbative function of the Collins-Soper-Sterman (CSS) formalism, which resums large logarithmic terms from multiple soft gluon ...

Leptoproduction of heavy quarks. II. A unified QCD formulation of charged and neutral current processes from fixed-target to collider energies. [PDF]
Physical Review D, Particles and fields, 1993 A unified QCD formulation of leptoproduction of massive quarks in charged current and neutral current processes is described. This involves adopting consistent factorization and renormalization schemes which encompass both vector-boson-gluon-fusion ...

Exact quantization conditions for the relativistic Toda lattice [PDF]
, 2015 A bstractInspired by recent connections between spectral theory and topological string theory, we propose exact quantization conditions for the relativistic Toda lattice of N particles. These conditions involve the Nekrasov-Shatashvili free energy, which

Resumming double non-global logarithms in the evolution of a jet
Journal of High Energy Physics, 2018 We consider the Banfi-Marchesini-Smye (BMS) equation which resums ‘non-global’ energy logarithms in the QCD evolution of the energy lost by a pair of jets via soft radiation at large angles.

Higher order and anisotropic hydrodynamics for Bjorken and Gubser flows [PDF]
Physical Review C, 2018 We study the evolution of hydrodynamic and nonhydrodynamic moments of the distribution function using anisotropic and third-order Chapman-Enskog hydrodynamics for systems undergoing Bjorken and Gubser flows. The hydrodynamic results are compared with the

Pion and kaon parton distributions in the QCD instanton vacuum [PDF]
, 2020 We discuss a general diagrammatic description of n-point functions in the QCD instanton vacuum that resums planar diagrams, and enforces gauge invariance and spontaneously broken chiral symmetry.

Restricted Tweedie stochastic block models
Canadian Journal of Statistics, EarlyView.Abstract The stochastic block model (SBM) is a widely used framework for community detection in networks, where the network structure is typically represented by an adjacency matrix. However, conventional SBMs are not directly applicable to an adjacency matrix that consists of nonnegative zero‐inflated continuous edge weights.
