B → π and B → K Transitions from QCD Sum Rules on the Light - Cone Patricia

FERMILAB–PUB–98/067–T (extended version) CERN–TH/98–215 hep-ph/9802394 Abstract: I calculate the form factors describing semileptonic and penguin-induced decays of B mesons into light pseudoscalar mesons. The form factors are calculated from QCD sum rules on the light-cone including contributions up to twist 4, radiative corrections to the leading twist contribution and SU(3)-breaking effects. ...

What Is the Upper Limit on the Lightest Supersymmetric

In this talk the question of what is the upper bound on the lightest supersymmetric Higgs mass, mh is addressed. This question is relevant since experimental lower bounds on mh might implement, in the near future, exclusion of supersymmetry. By imposing (perturbative) unification of the gauge couplings at some high scale > ∼ 10 GeV, we have found that for a top-quark mass Mt = 175 GeV, and depe...

How particles emerge from decaying classical fields in heavy ion collisions: towards a kinetic description of the Glasma

We develop the formalism discussed previously in hep-ph/0601209 and hep-ph/0605246 to construct a kinetic theory that provides insight into the earliest “Glasma” stage of a high energy heavy ion collision. Particles produced from the decay of classical fields in the Glasma obey a Boltzmann equation whose novel features include an inhomogeneous source term and new contributions to the collision ...
