Exclusive radiative and electroweak b->d and b->s penguin decays at NLO
M. Beneke, Th. Feldmann, D. Seidel
We provide Standard Model expectations for the rare radiative decays B->K^* gamma, B->rho gamma and B-> omega gamma, and the electroweak penguin decays B->K^* l^+ l^- and B->rho l^…
Power corrections to B\to X_u l ν(X_sγ) decay spectra in the "shape-function" region
M. Beneke, F. Campanario, T. Mannel +1
Using soft-collinear effective theory (SCET), we examine the 1/m_b corrections to the factorization formulas for inclusive semi-leptonic B decays in the endpoint region, where the…
Towards pair production near threshold with unstable particle effective theory
M. Beneke, N. Kauer, A. Signer +1
We illustrate the use of effective theory techniques to describe processes involving unstable particles close to resonance. First, we present the main ideas in the context of a sca…
Loop corrections to sub-leading heavy quark currents in SCET
M. Beneke, Y. Kiyo, D. s. Yang
We compute the one-loop (hard) matching correction to heavy-to-light transition currents in soft-collinear effective theory (SCET) to sub-leading power in the SCET expansion parame…
Effective theory calculation of resonant high-energy scattering
M. Beneke, A. P. Chapovsky, A. Signer +1
Tests of the standard model and its hypothetical extensions require precise theoretical predictions for processes involving massive, unstable particles. It is well-known that ordin…
