Three-Parton Contributions to B --> M_1 M_2 Annihilation at Leading Order
Christian M. Arnesen, Ira Z. Rothstein, Iain W. Stewart
We compute annihilation amplitudes for charmless B decays that are proportional to the three-parton twist-3 light meson distribution amplitude phi_{3M}(x1,x2) with an active gluon.…
Power Corrections in Charmless Nonleptonic B-Decays: Annihilation is Factorizable and Real
Christian M. Arnesen, Zoltan Ligeti, Ira Z. Rothstein +1
We classify LambdaQCD/mb power corrections to nonleptonic B-> M1 M2 decays, where M1 and M2 are charmless non-isosinglet mesons. Using recent developments in soft-collinear effecti…
Towers of Gravitational Theories
Walter D. Goldberger, Ira Z. Rothstein
In this essay we introduce a theoretical framework designed to describe black hole dynamics. The difficulties in understanding such dynamics stems from the proliferation of scales…
The Hyperfine Einstein-Infeld-Hoffmann Potential
Rafael A. Porto, Ira Z. Rothstein
We use recently developed effective field theory techniques to calculate the third order post-Newtonian correction to the spin-spin potential between two spinning objects. This cor…
Falsifying Models of New Physics Via WW Scattering
Jacques Distler, Benjamin Grinstein, Rafael A. Porto +1
We show that the coefficients of operators in the electroweak chiral Lagrangian can be bounded if the underlying theory obeys the usual assumptions of Lorentz invariance, analytici…
Asymptotics of d-dimensional Kaluza-Klein black holes: beyond the Newtonian approximation
Yi-Zen Chu, Walter D. Goldberger, Ira Z. Rothstein
We study the thermodynamics of small black holes in compactified spacetimes of the form R^(d-1)x S^1. This system is analyzed with the aid of an effective field theory (EFT) formal…
