Factorization formula connecting the Λ b LCDA in QCD and boosted HQET
Journal of High Energy PhysicsLight-cone distribution amplitudes (LCDAs) are essential to precision phenomenology in heavy baryon decays. In this work, we derive a factorization formula connecting the leading-twist QCD LCDA to the boosted HQET LCDA of the Λ b baryon in the peak ...

, 2011 We discuss perturbative O(g2a) matching with static heavy quarks and domainwall light quarks for lattice operators relevant to B-meson decays and B0–¯B 0 mixing. The chiral symmetry of the light domain-wall quarks does not prohibit operator mixing at O(a)

The Revival of Kaon Flavour Physics
EPJ Web of Conferences, 2016 After years of silence we should witness in the rest of this decade and in the next decade the revival of kaon flavour physics. This is not only because of the crucial measurements of the branching ratios for the rare decays K+ → π+vv̄ and KL → π0vv̄ by ...

Picturing perturbative parton cascades in QCD matter
, 2014 Based on parametric reasoning, we provide a simple dynamical picture of how a perturbative parton cascade, in interaction with a QCD medium, fills phase space as a function of ...

Perturbation theory of non-perturbative QCD
, 2015 Perturbation theory is shown to be working in the IR limit of pure SU(3) Yang-Mills theory in Landau gauge by an unconventional setting of the perturbative expansion. A dynamical mass is predicted for the gluon and the lattice data are reproduced fairly well by a second-order expansion, without any free parameter.

Large N Behaviour of Perturbative QCD Coupling
, 1982 International audienceA correspondence between perturbative QCD in an axial gauge and dual topological unitarization (DTU) scheme is expressed by linking the QCD scale A to N, the number of flavors or colors supposed to be large through a relation which ...
