Two-body B Meson Decays to eta and eta': Observation of B->eta K*
The CLEO Collaboration, S. J. Richichi
In a sample of 19 million produced B mesons, we have observed the decays B -> eta K* and improved our previous measurements of B -> eta'K. The branching fractions we measure for th…
Single Top Quark Production at the LHC: Understanding Spin
Gregory Mahlon, Stephen Parke
We show that the single top quarks produced in the Wg-fusion channel at a proton-proton collider at a center-of-mass energy sqrt{s}=14 TeV posses a high degree of polarization in t…
Calogero-Moser systems and Hitchin systems
J. C. Hurtubise, E. Markman
We exhibit the elliptic Calogero-Moser system as a Hitchin system of G-principal Higgs pairs. The group G, though naturally associated to any root system, is not semi-simple. We th…
Generalized Stable Multivariate Distribution and Anisotropic Dilations
D. Schertzer, M. Larcheveque, J. Duan +1
After having closely re-examined the notion of a Lévy's stable vector, it is shown that the notion of a stable multivariate distribution is more general than previously defined. In…
A Higgs or Not a Higgs? What to Do if You Discover a New Scalar Particle
C. P. Burgess, J. Matias, M. Pospelov
We show how to systematically analyze what may be inferred should a new scalar particle be discovered in collider experiments. Our approach is systematic in the sense that we perfo…
Coherence Time Effects on J/psi Production and Suppression in Relativistic Heavy Ion Collisions
Charles Gale, Sangyong Jeon, Joseph Kapusta
Using a coherence time extracted from high precision proton-nucleus Drell-Yan measurements and a nuclear absorption cross section extracted from pA charmonium production experiment…
