Brane Inflation
Gia Dvali, S. -H. Henry Tye
We present a novel inflationary scenario in theories with low scale (TeV) quantum gravity, in which the standard model particles are localized on the branes whereas gravity propaga…
Flavor Violation in Theories with TeV Scale Quantum Gravity
Zurab Berezhiani, Gia Dvali
We study the effects of possible flavor-violating operators in theories with the TeV scale quantum gravity, in which the ordinary matter is localized on a 3-brane embedded in the s…
High Temperature Symmetry Breaking, SUSY Flat Directions, and the Monopole Problem
Gia Dvali, Lawrence M. Krauss
Supersymmetric flat directions allow a generic counterexample to the phenomenon of symmetry restoration at high temperatures. We show that (exponentially) large VEVs can be develop…
Effective QCD Interactions of CP-odd Higgs Bosons at Three Loops
K. G. Chetyrkin, B. A. Kniehl, M. Steinhauser +1
In the virtual presence of a heavy quark t, the interactions of a CP-odd scalar boson A, with mass M_A << 2M_t, with gluons and light quarks can be described by an effective Lagran…
Radiative Corrections to W and Quark Propagators in the Resonance Region
M. Passera, A. Sirlin
It is shown that conventional mass renormalization, when applied to photonic or gluonic corrections to unstable particle propagators, leads to non-convergent series in the resonanc…
Differences Between the Pole and On-Shell Masses and Widths of the Higgs Boson
B. A. Kniehl, A. Sirlin
The differences between the on-shell mass and width of the Higgs boson and their pole counterparts are evaluated in leading order. For a heavy Higgs boson, they are found to be sen…
