Leading SU(3) breaking in lightcone distribution amplitudes

Chul Kim, Adam K. Leibovich

The lightcone formalism including SU(3) breaking effects for the light pseudoscalar mesons is studied using soft-collinear effective theory (SCET), where the conformal symmetries n…

Nonperturbative Charming Penguin Contributions to Isospin Asymmetries in Radiative B decays

Chul Kim, Adam K. Leibovich, Thomas Mehen

Recent experimental data on the radiative decays B -> V gamma, where V is a light vector meson, find small isospin violation in B -> K^* gamma while isospin asymmetries in B -> rho…

Anti-B --> X(s) gamma in two universal extra dimensions

Ayres Freitas, Ulrich Haisch

We calculate the leading order corrections to the anti-B --> X(s) gamma decay in the standard model with two large flat universal extra dimensions. We find that the contributions i…

Probing electroweak physics using B -> XM decays in the endpoint region

Junegone Chay, Chul Kim, Adam K. Leibovich +1

Using soft-collinear effective theory we describe at leading order in 1/m_b all the semi-inclusive hadronic B -> XM decays near the endpoint, where an energetic light meson M recoi…

Production of a sterile species via active-sterile mixing: an exactly solvable model

D. Boyanovsky

The production of a sterile species via active-sterile mixing in a thermal medium is studied in an exactly solvable model. The \emph{exact} time evolution of the sterile distributi…

The color-singlet contribution to e^+ e^- ->J/psi + X at the endpoint

Adam K Leibovich, Xiaohui Liu

Recent observations of the J/psi spectrum produced in e^+e^- collisions at the Upsilon(4S) resonance are in conflict with fixed-order calculations using Non-Relativsitic QCD effect…
