Soft-collinear gravity beyond the leading power

چکیده
We construct "soft-collinear gravity", the effective field theory which describes interaction of collinear and soft gravitons with matter (and themselves), to all orders in soft-collinear power expansion. Despite absence divergences gravity at leading power, construction exhibits remarkable similarities QCD (gauge fields). It reveals an emergent background gauge symmetry, allows for a manifestly gauge-invariant representation interactions terms covariant derivative, Riemann tensor, generalisation light-cone metric field. The symmetries control both unsuppressed components inherent inhomogeneity $\lambda$ invariant objects orders, resulting consistent

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...

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.

We study the power corrections to the cross-section of Drell-Yan production within the Wilson line approach and apply the methods of QCD asymptotic dynamics to identify the leading renormalon
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...
