Jet quenching phenomenology from soft-collinear effective theory with Glauber gluons.
We present the first application of a recently developed effective theory of jet propagation in matter, soft-collinear effective theory with Glauber gluons (SCET_{G}), to inclusive hadron suppression in nucleus-nucleus collisions at RHIC and the LHC. SCET_{G}-based splitting kernels allow us to go beyond the traditional energy loss approximation and unify the treatment of vacuum and medium-indu...
متن کاملSoft - Collinear - Effective - Theory
We analyze the charmless two-body B → V P decays in the soft-collinear-effective-theory (SCET), where V (P ) denotes a light vector (pseudoscalar) meson. Using the current experimental data, we find two solutions in χ fit for the 16 non-perturbative inputs responsible for the 87 B → PP and B → V P decay channels in SU(3) symmetry. Chirally enhanced penguins can only change several charming peng...
متن کاملSoft Collinear Effective Theory
In this talk I review soft collinear effective theory. After a discussion of the formalism and properties of the effective field theory, I turn to phenomenology. I present results on colorsuppressed B → D decays, and on the Υ radiative decay spectrum.
متن کاملNotes on the Soft-Collinear Effective Theory
Contents 1 Introduction to SCET 4 1. 1 Introduction to SCET These notes provide reading material on the Soft-Collinear Effective Theory (SCET) for Chrisitian's SCET Lectures in TASI 2013. They also served as lecture notes for Iain's 2013 EFT course taught at MIT. The notes assume some familiarity with various basic effective field theory (EFT) concepts, including power counting with operator di...
متن کاملThe Soft-Collinear Effective Field Theory
In general, to understand hadronic uncertainties we need a separation of short p ∼ Q and long p ∼ ΛQCD distance fluctuations. For processes in QCD with momentum transfers Q ≫ ΛQCD, the short distance part is calculable in terms of Wilson coefficients or hard scattering functions. The long distance contributions can be arranged into universal non-perturbative matrix elements which can be extract...
