Radiative Corrections to Neutralino and Chargino Masses in the Minimal Supersymmetric Model
Damien Pierce, Aris Papadopoulos
We determine the neutralino and chargino masses in the MSSM at one-loop. We perform a Feynman diagram calculation in the on-shell renormalization scheme, including quark/squark and…
Spacetime Symmetries and Semiclassical Amplitudes
Thomas M. Gould, Stephen D. H. Hsu
We examine the spacetime symmetries of forward scattering. These symmetries have non-trivial consequences for any class of configurations which might dominate the…
Closing the Windows on Mev Tau Neutrinos
K. S. Babu, T. M. Gould, I. Z. Rothstein
In this note, we analyze various constraints on the ``visible'' decay modes of a massive neutrino, and , where $ν^…
Twist Points as Branch Points for the QCD String
Stephen G. Naculich, Harold A. Riggs, Howard J. Schnitzer
We show that the string representation of the QCD partition function satisfies, by virtue of a Young-tableau-transposition symmetry, the topological constraint that any branche…
Nonperturbative Contributions to the Inclusive Rare Decays and
Adam F. Falk, Michael Luke, Martin J. Savage
We discuss nonperturbative contributions to the inclusive rare decays and . We employ an operator product expansion and the heavy quark effect…
Destabilizing Divergences in Supergravity-Coupled Supersymmetric Theories
Jonathan Bagger, Erich Poppitz
Nonrenormalizable couplings in supergravity-coupled supersymmetric theories can give rise to power-law divergences that destabilize the weak-scale hierarchy. For the case of the st…
Semiclassical transition in ϕ^4 theory
Alexander Kyatkin
We have shown an example of semiclassical transition in theory with positive coupling constant. This process can be described by the classical -invariant solution, co…
The Strongly Interacting System: Gold--Plated Modes
J. Bagger, V. Barger, K. Cheung +5
In this paper we survey the signals and backgrounds for a strongly-interacting electroweak symmetry breaking sector at hadron supercolliders in the TeV region. We study the process…
Astrophysical Limit on the Deformation of the Poincare Group
G. Domokos, S. Kovesi--Domokos
The deformed Poincaré group contains a characteristic mass, . At energies exceeding , deviations from the special theory of relativity become significant. However, small devi…
Multi Particle Semiclassical Process in \PHI^4 Theory
Alexander Kyatkin
We have shown an example of semiclassical transition in ϕ^4 model with positive coupling constant. This process describes a semiclassical transition between two coherent states wit…
Two-dimensional Yang-Mills Theories Are String Theories
S. G. Naculich, H. A. Riggs, H. J. Schnitzer
We show that two-dimensional SO(N) and Sp(N) Yang-Mills theories without fermions can be interpreted as closed string theories. The terms in the 1/N expansion of the partition func…
On the Treatment of Neutrino Oscillations Without Resort to Weak Eigenstates
C. Giunti, C. W. Kim, J. A. Lee
We discuss neutrino oscillations in the framework of the quantum field theory without introducing the concept of neutrino weak eigenstates. The external particles are described by…
Semiclassical Scattering in Yang-Mills Theory
Thomas M. Gould, Erich R. Poppitz
A classical solution to the Yang-Mills theory is given a new semiclassical interpretation. The boundary value problem on a complex time contour which arises from the semiclassical…
Complex Time Solutions with Nontrivial Topology and Multi Particle Scattering in Yang-Mills Theory
Thomas M. Gould, Erich R. Poppitz
A classical solution to the Yang-Mills theory is given a new semiclassical interpretation in terms of particle scattering. It solves the complex time boundary value problem, which…
Fermion and Anti-Fermion Effective Masses in High Temperature Gauge Theories in -Asymmetric Background
A. Erdas, C. W. Kim, J. A. Lee
We calculate the splitting between fermion and anti-fermion effective masses in high temperature gauge theories in the presence of a non-vanishing chemical potential due to the $CP…
A Twistor Formulation of the Non-Heterotic Superstring with Manifest Worldsheet Supersymmetry
A. Galperin, E. Sokatchev
We propose a new formulation of the type II superstring which is manifestly invariant under both target-space supersymmetry and worldsheet super reparametriza…
Decoupling in Non-Perturbative Background Fields: the Thermal Sphaleron
Thomas M. Gould, I. Z. Rothstein
Standard decoupling of heavy fermions may fail when there are non-perturbative variations in a scalar field which gives masses to the fermions. One situation of phenomenological re…
Inelastic Channels in WW Scattering
S. G. Naculich, C. -P. Yuan
If the electroweak symmetry-breaking sector becomes strongly interacting at high energies, it can be probed through longitudinal scattering. We present a model with many inelas…
Fermion Density Induced Instability of the W-Boson Pair Condensate in Strong Magnetic Field
Erich R. Poppitz
The electroweak vacuum structure in an external magnetic field close to the lower critical value is considered at finite fermion density. It is shown that the leading effect of the…
Third Generation Effects on Fermion Mass Predictions in Supersymmetric Grand Unified Theories
Stephen G. Naculich
Relations among fermion masses and mixing angles at the scale of grand unification are modified at lower energies by renormalization group running induced by gauge and Yukawa coupl…
