Measurement of the form-factor ratios for D^+ -> \overline K^{*0}e^+ν_e

Fermilab E791 Collaboration, E. M. Aitala

We present a measurement of the form-factor ratios r_V=V(0)/A_1(0) and r_2=A_2(0)/A_1(0) for the decay D^+ -> \overline K^{*0} e^+ ν_e. The measurement is based on a signal of appr…

The Status of the Minimal Supersymmetric Standard Model and Beyond

Howard E. Haber

The minimal supersymmetric extension of the Standard Model (MSSM) is reviewed. In the most general framework with minimal field content and R-parity conservation, the MSSM is a 124…

Some Issues in Gauge Mediation

Michael Dine

After briefly reviewing some arguments in favor of high scale and low scale supersymmetry breaking, I discuss a possible solution of the -problem of gauge mediated models.

chi^2 Analysis of Supersymmetric Models

Damien M. Pierce, Jens Erler

We discuss the results of a global fit to precision data in supersymmetric models. We consider both gravity- and gauge-mediated models. As the superpartner spectrum becomes light,…

Aspects of SU(N_c) Gauge Theories in the Limit of Small Number of Colors

Stanley J. Brodsky, Patrick Huet

We investigate properties of the color space of gauge theories in the limit of small number of colors and large number of flavors. More generally, we introd…

Supersymmetric loop effects

P. H. Chankowski, S. Pokorski

We review the loop effects of the low energy supersymmetry. The global success of the Standard Model rises two related questions: how strongly the mass scales of the superpartners…

Higgs Boson Masses and Couplings in the Minimal Supersymmetric Model

Howard E. Haber

The Higgs sector of the Minimal Supersymmetric Model (MSSM) is a CP-conserving two-Higgs doublet model that depends, at tree-level, on two Higgs sector parameters. In order to accu…

An Inflaton Candidate in Gauge Mediated Supersymmetry Breaking

Michael Dine, Antonio Riotto

Inflation, as currently understood, requires the presence of fields with very flat potentials. Supersymmetric models in which supersymmetry breaking is communicated by supergravity…

QED One-loop Corrections to a Macroscopic Magnetic Dipole

Jeremy S. Heyl, Lars Hernquist

We consider the field equations of a static magnetic field including one-loop QED corrections, and calculate the corrections to the field of a magnetic dipole. PACS: 12.20.Ds, 97.6…

Birefringence and Dichroism of the QED Vacuum

Jeremy S. Heyl, Lars Hernquist

We use an analytic form for the Heisenberg-Euler Lagrangian to calculate the birefringent and dichroic properties of the vacuum for arbitrarily strong wrenchless fields. PACS : 12.…

LEP Limits on CP-Violating Non-Minimal Higgs Sectors

J. F. Gunion, B. Grzadkowski, H. E. Haber +1

We derive a sum rule which shows how to extend LEP limits on the masses of the lightest CP-even and CP-odd Higgs bosons of a CP-conserving two-Higgs-doublet model to any two Higgs…

Sneutrino Mixing Phenomena

Yuval Grossman, Howard E. Haber

In any model with nonzero Majorana neutrino masses, the sneutrino and antisneutrino of the supersymmetric extended theory mix. We outline the conditions under which sneutrino-antis…
