Dijet Production at Large Rapidity Intervals

Vittorio Del Duca, Carl R. Schmidt

We examine dijet production at large rapidity intervals at Tevatron energies, by using the theory of Lipatov and collaborators which resums the leading powers of the rapidity inter…

Particle Astrophysics from the Particle Perspective

Michael Dine

In this talk I discuss several topics at the interface of particle physics and astrophysics/cosmology. These include the problem of dark matter and two popular dark matter candidat…

Vector Leptoquark Production at Hadron Colliders

J. Hewett, T. Rizzo, S. Pakvasa +2

We explore the production of vector leptoquarks () at the Tevatron, LHC, and SSC through both quark-antiquark and gluon fusion: . The cross sections are fou…

Detecting Technibaryon Dark Matter

John Bagnasco, Michael Dine, Scott Thomas

The technibaryon constitutes a possible dark matter candidate. Such a particle with electroweak quantum numbers is already nearly ruled out as the dominant component of the galacti…

The Renormalization-Group Improved Higgs Sector of the Minimal Supersymmetric Model

Howard E. Haber, Ralf Hempfling

In the minimal supersymmetric model (MSSM) all Higgs self-coupling parameters are related to gauge couplings at tree-level. Leading-logarithmic radiative corrections to these quant…

Discovering Supersymmetry with Like-sign Dileptons

R. Michael Barnett, John F. Gunion, Howard E. Haber

Supersymmetry may be discovered at hadron colliders by searching for events similar to the top quark signal of two isolated leptons. In the case of gluino production, the most dist…

Constraints on CP violation in the Higgs sector from the parameter

Alex Pomarol, Roberto Vega

We discuss the relation between the CP symmetry and the custodial symmetry in the Higgs sector. In particular, we show that CP violation in the Higgs-gauge sector is allowe…

Flavor Symmetries and The Problem of Squark Degeneracy

M. Dine, A. Kagan, R. G. Leigh

If supersymmetry exists at low energies, it is necessary to understand why the squark spectrum exhibits sufficient degeneracy to suppress flavor changing neutral currents. In this…

Dynamical Supersymmetry Breaking at Low Energies

Michael Dine, Ann E. Nelson

Conventional approaches to supersymmetric model building suffer from several naturalness problems: they do not explain the large hierarchy between the weak scale and the Planck mas…

Supersymmetry and the Nelson-Barr Mechanism

M. Dine, A. Kagan, R. G. Leigh

One possible solution to the strong CP problem is that CP is an exact symmetry, spontaneously broken at some scale. Some years ago, Nelson and Barr suggested a mechanism for obtain…

Z\rightarrow A^0 A^0ν\barνe^+e^-\rightarrow A^0 A^0 Z$ in Two Higgs Doublet Models

Howard E. Haber, Yosef Nir

In LEP searches for the neutral CP-odd scalar of a multi-Higgs doublet model, experimenters have searched for (where is the lightest CP-even scal…
