Medium-induced fragmentation and equilibration of highly energetic partons
Journal of High Energy Physics, 2021 We investigate the energy loss and equilibration of highly energetic particles/jets inside a QCD medium. Based on an effective kinetic description of QCD, including 2 ↔ 2 elastic processes, radiative 1 ↔ 2 processes, as well as the back-reaction of jet ...

Relating Meson and Baryon Fragmentation Functions by Shower-Parton Recombination
, 2006 We relate the fragmentation functions of partons into mesons and baryons in the framework of recombination of shower partons. The results are in reasonable agreement with the data.

Subleading effects in soft-gluon emission at one-loop in massless QCD
Journal of High Energy Physics, 2023 We elucidate the structure of the next-to-leading-power soft-gluon expansion of arbitrary one-loop massless-QCD amplitudes. The expansion is given in terms of universal colour-, spin- and flavour-dependent operators acting on process-dependent gauge ...

Monte Carlo approach for hadron azimuthal correlations in high energy proton and nuclear collisions
, 2012 We use a Monte Carlo approach to study hadron azimuthal angular correlations in high energy proton-proton and central nucleus-nucleus collisions at the BNL Relativistic Heavy Ion Collider (RHIC) energies at mid-rapidity. We build a hadron event generator

TMD parton distributions from parton showers [PDF]
Proceedings of XXVII International Workshop on Deep-Inelastic Scattering and Related Subjects — PoS(DIS2019), 2019 We present the determination of Transverse Momentum Dependent (TMD) parton distributions from Monte Carlo parton showers. We investigate the effective TMD distributions obtained from the PYTHIA8 and HERWIG6 parton showers and compare them to the TMD distributions determined within the Parton Branching method.

Glauber phases in non-global LHC observables: resummation for quark-initiated processes
Journal of High Energy Physics, 2023 It has been known for many years that jet cross sections at hadron colliders exhibit double-logarithmic corrections starting at four-loop order, arising from two soft Glauber-gluon interactions between the two colliding partons. The resummation of these “

Parton showers from the dipole formalism
, 2007 We present an implementation of a parton shower algorithm for hadron colliders and electron-positron colliders based on the dipole factorisation formulae. The algorithm treats initial-state partons on equal footing with final-state partons.

Parton distribution functions [PDF]
Nuclear Physics B - Proceedings Supplements, 1997 Parton distribution functions give the probability to find partons (quarks and gluons) in a hadron as a function of the fraction x of the proton's momentum carried by the parton. They are conventionally defined in terms of matrix elements of certain operators.

Cytoskeleton, EarlyView.ABSTRACT Cooperativity between cytoskeletal proteins is crucial for spatiotemporal coordination in biological processes, like oogenesis. In mammalian and Drosophila oogenesis, proper assembly and function of actin networks require coordination between actin assembly factors Spire and formins, as well as actin‐associated proteins like myosins and Rab ...
