Quantum Chromodynamics, the theory of quarks and gluons, whose interactions can be
described by a local SU (3) gauge symmetry with charges called “color quantum numbers” …

Most inclusive rare B decays are important modes of flavor physics due to the small hadronic
uncertainties. In this article, the author gives a status report on such decays, highlighting …

The factorization of soft and ultrasoft gluons from collinear particles is shown at the level of
operators in an effective field theory. Exclusive hadronic factorization and inclusive partonic …

The series Lecture Notes in Physics (LNP), founded in 1969, reports new developments in
physics research and teaching-quickly and informally, but with a high quality and the explicit …

We consider processes which produce final state hadrons whose energy is much greater
than their mass. In this limit interactions involving collinear fermions and gluons are …

In this paper we show how gauge symmetries in an effective theory can be used to simplify
proofs of factorization formulas in highly energetic hadronic processes. We use the soft …

A comprehensive study of exclusive hadronic B-meson decays into final states containing
two pseudoscalar mesons (PP) or a pseudoscalar and a vector meson (PV) is presented …

We calculate the CP-averaged branching ratios and CP-violating asymmetries of a number
of two-body charmless hadronic decays B¯ s 0→ PP, PV, VV in the perturbative QCD …

We consider high spin operators. We give a general argument for the logarithmic scaling of
their anomalous dimensions which is based on the symmetries of the problem. By an …

We study a Lagrangian formalism that avoids double counting in effective field theories
where distinct fields are used to describe different infrared momentum regions for the same …
