Linearized Gravity in Brane Backgrounds
S. B. Giddings, E. Katz, L. Randall
A treatment of linearized gravity is given in the Randall-Sundrum background. The graviton propagator is found in terms of the scalar propagator, for which an explicit integral exp…
Supersymmetric Partners of Oblique Corrections
Emanuel Katz, Lisa Randall, Shufang Su
We discuss the violation of the equality of the gauge coupling and gaugino coupling in the presence of soft supersymmetry breaking. Although this is a hard supersymmetry breaking e…
Supersymmetric Partners of Oblique Corrections
L. Randall, E. Katz, S. Su
We discuss a potential new probe of supersymmetric physics. In particular, we discuss the possibility of measuring hard supersymmetry violation which occurs at one loop through "su…
Constraints on a Massive Dirac Neutrino Model
Thomas Wynter, Lisa Randall
We examine constraints on a simple neutrino model in which there are three massless and three massive Dirac neutrinos and in which the left handed neutrinos are linear combinations…
Chiral Perturbation Theory for and Semileptonic Transition Matrix Elements at Zero Recoil
L. Randall, M. B. Wise
Heavy quark symmetry predicts the value of and transition matrix elements of the current , at zero recoil (where in the…
The QCD Scale in the Heavy Quark Expansion
Lisa Randall, Eric Sather
We argue that consistency of the combined heavy quark and chiral effective lagrangian requires the QCD scale which multiplies in the heavy quark expansion to be the chiral sy…
