Abelian Decomposition and Monopole Condensation in QCD
EPJ Web of Conferences, 2018 We demonstrate the monopole condensation in QCD using the Abelian decomposition. The Abelian decomposition decomposes the gluons to the color neutral binding gluons (the neurons and the monopoles) and the colored valence gluons (the chromons), and shows ...

Scalar coupling evolution in a non-perturbative QCD resummation scheme
Physics Letters B, 2015 We compute the Standard Model scalar coupling (λ) evolution in a particular QCD resummation scheme, where the QCD coupling becomes infrared finite due to the presence of a dynamically generated gluon mass, leading to the existence of a non-perturbative ...

Heavy-quark fragmentation functions at next-to-leading perturbative QCD [PDF]
, 2016 It is well known that the dominant mechanism to produce hadronic bound states with large transverse momentum is fragmentation. This mechanism is described by the fragmentation functions (FFs) which are the universal and process-independent functions ...

Fixing the conformal window in QCD [PDF]
, 2000 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. A natural way to disentangle ``perturbative'' from ``non-perturbative'' contributions to

Drell-Yan lepton angular distributions in perturbative QCD [PDF]
, 2016 We present a comprehensive comparison of the available experimental data for the Drell-Yan lepton angular coefficients $\ensuremath{\lambda}$ and $\ensuremath{\nu}$ to calculations at leading and next-to-leading order of perturbative QCD.

Effective locality and gauge invariance
EPJ Web of Conferences, 2018 A few years ago, based on standard functional manipulations, an unexpected property was proven to be satisfied by the fermionic Green's functions of QCD, and dubbed effective locality.

MS renormalization of S-wave quarkonium wavefunctions at the origin
Journal of High Energy Physics, 2020 We compute S-wave quarkonium wavefunctions at the origin in the MS ¯ $$ \overline{\mathrm{MS}} $$ scheme based on nonrelativistic effective field theories.

Soft-drop grooming for hadronic event shapes
Journal of High Energy Physics, 2021 Soft-drop grooming of hadron-collision final states has the potential to significantly reduce the impact of non-perturbative corrections, and in particular the underlying-event contribution.

Understanding the penguin amplitude in $B \to \phi K$ decays [PDF]
, 2001 We calculate branching ratios for pure penguin decay modes, $B\to \phi K$ decays using perturbative QCD approach. Our results of branching ratios are consistent with the experimental data and larger than those obtained from the naive factorization ...

Improved estimates of the B-(s) -> VV decays in perturbative QCD approach [PDF]
, 2015 We reexamine the branching fractions, CP asymmetries, and other observables in a large number of B-q -> VV(q = u, d, s) decays in the perturbative QCD approach, where V denotes a light vector meson (rho, K*,omega, phi)The essential difference between ...
