Isospin violation in e+ e- --> B Bbar
Roland Kaiser, Aneesh V. Manohar, Thomas Mehen
The ratio of the B+ B- and B0 B0bar production rates in e+ e- annihilation is computed as a function of the B meson velocity and BB* pi coupling constant, using a non-relativistic…
Gauge Fields and Scalars in Rolling Tachyon Backgrounds
Thomas Mehen, Brian Wecht
We investigate the dynamics of gauge and scalar fields on unstable D-branes with rolling tachyons. Assuming an FRW metric on the brane, we find a solution of the tachyon equation o…
The Leading Particle Effect from Heavy-Quark Recombination
Eric Braaten, Yu Jia, Thomas Mehen
The leading particle effect in charm hadroproduction is an enhancement of the cross section for a charmed hadron D in the forward direction of the beam when the beam hadron has a v…
Reparameterization Invariance for Collinear Operators
Aneesh V. Manohar, Thomas Mehen, Dan Pirjol +1
We discuss restrictions on operators in the soft-collinear effective theory (SCET) which follow from the ambiguity in the decomposition of collinear momenta and the freedom in the…
