Journal Article

We make use of recent results in effective theory and higher-order perturbative calculations to improve the theoretical predictions of the QCD contribution to the top-quark pair production forward-backward asymmetry at the Tevatron. In particular, we... Read More about Top-pair forward-backward asymmetry beyond next-to-leading order..

RG-improved single-particle inclusive cross sections and forward-backward asymmetry in tt¯tt¯ production at hadron colliders. (2011)
Journal Article

We use techniques from soft-collinear effective theory (SCET) to derive renormalization-group improved predictions for single-particle inclusive (1PI) observables in top-quark pair production at hadron colliders. In particular, we study the top-quark... Read More about RG-improved single-particle inclusive cross sections and forward-backward asymmetry in tt¯tt¯ production at hadron colliders..

Precision predictions for the t+t(bar) production cross section at hadron colliders. (2011)
Journal Article
Ahrens, V., Ferroglia, A., Neubert, M., Pecjak, B. D., & Yang, L. L. (2011). production cross section at hadron colliders. Physics Letters B, 703(2), 135-141. https://doi.org/10.1016/j.physletb.2011.07.058

We make use of recent results in effective theory and higher-order perturbative calculations to improve the theoretical predictions of the top-quark pair production cross section at hadron colliders. In particular, we supplement the fixed-order NLO c... Read More about Precision predictions for the t+t(bar) production cross section at hadron colliders..

Sum rule estimate of the subleading non-perturbative contributions to B s –B¯sB¯s mixing. (2011)
Journal Article

We use QCD sum rules to compute the matrix elements of the ΔB=2 operators appearing in the heavy-quark expansion of the width difference of the B s mass eigenstates. The main focus of our analysis is on the subleading operators R 2 and R 3, which app... Read More about Sum rule estimate of the subleading non-perturbative contributions to B s –B¯sB¯s mixing..
