P -wave contributions to B→ψππ decays in the perturbative QCD approach [PDF]
Physical Review D, 2018 We present the differential branching fractions for the $B\rightarrow \psi \pi\pi$ decays with the charmonia $\psi=J/\psi,\psi(2S)$ in the invariant mass of the $P$-wave pion pairs in the perturbative QCD approach.

Combining the small-x evolution and DGLAP for description of inclusive photon induced processes
European Physical Journal C: Particles and Fields, 2020 We study amplitudes of the inclusive photon induced high-energy processes: elastic Compton scattering off hadrons and photoproduction. Although description of these amplitudes includes both non-perturbative and perturbative contributions, QCD ...

W-Boson Production in Association with a Jet at Next-to-Next-to-Leading Order in Perturbative QCD. [PDF]
Physical Review Letters, 2015 We present the complete calculation of W-boson production in association with a jet in hadronic collisions through next-to-next-to-leading order (NNLO) in perturbative QCD. To cancel infrared divergences, we discuss a new subtraction method that exploits

Rapidity gaps in perturbative QCD [PDF]
Physical Review D, 1997 We analyze diffractive deep inelastic scattering within perturbative QCD by studying lepton scattering on a heavy quark target. Simple explicit expressions are derived in impact parameter space for the photon wave function and the scattering cross sections corresponding to single and double Coulomb gluon exchange.

Soft integrals and soft anomalous dimensions at N3LO and beyond
Journal of High Energy Physics, 2022 We calculate soft phase-space and loop master integrals for the computation of color-singlet cross sections through N3LO in perturbative QCD. Our results are functions of homogeneous transcendental weight and include the first nine terms in the expansion

The Odderon in QCD with running coupling
Journal of High Energy Physics, 2020 Starting from the leading Odderon solution of the three gluon system in perturbative QCD we introduce, as a first step towards the transition to the non-perturbative region, an infrared cutoff and use the running QCD coupling constant.

Conformal window and Landau singularities [PDF]
, 2001 A physical characterization of Landau singularities is emphasized, which should trace the lower boundary N_f^* of the conformal window in QCD and supersymmetric QCD.

Alzheimer's &Dementia, Volume 19, Issue 12, Page 5447-5470, December 2023., 2023 Abstract INTRODUCTION A hallmark of Alzheimer's disease (AD) is the aggregation of proteins (amyloid beta [A] and hyperphosphorylated tau [T]) in the brain, making cerebrospinal fluid (CSF) proteins of particular interest. METHODS We conducted a CSF proteome‐wide analysis among participants of varying AT pathology (n = 137 participants; 915 proteins ...

Shear Viscosity of Quark-Gluon Plasma in Weak Magnetic Field in Perturbative QCD: Leading Log [PDF]
, 2017 We compute the shear viscosity of two-flavor QCD plasma in an external magnetic field in perturbative QCD at leading log order, assuming that the magnetic field is weak or soft: $eB\sim g^4\log(1/g)T^2$.
