A wide scalar neutrino resonance and b\bar{b} production at LEP

Jens Erler, Jonathan L. Feng, Nir Polonsky

In supersymmetric models with R-parity violation, scalar neutrinos may be produced as s-channel resonances in e^+e^- colliders. We note that within current constraints, the scalar…

Neutrinoless Double Beta Decay and its "Inverse"

Clemens A. Heusch, Peter Minkowski

Recent considerations by these authors pointed out the attractive features which a search for the exchange of heavy Majorana neutrinos could have for solving the mass and the lepto…

Will at least one of the Higgs bosons of the next-to-minimal supersymmetric extension of the Standard Model be observable at LEP2 or the LHC?

J. F. Gunion, H. E. Haber, T. Moroi

We demonstrate that there are regions of parameter space in the next-to-minimal (i.e. two-Higgs-doublet, one-Higgs-singlet superfield) supersymmetric extension of the SM for which…

Cosmological Structure Formation With and Without Hot Dark Matter

Joel Primack

Cold + Hot Dark Matter (CHDM) is perhaps the best theory of cosmic structure formation {\it if} the cosmological matter density is near critical (i.e., ) and {\it if…

Measurement of the proton and deuteron structure functions, F2p and F2d, and of the ratio sigma(L)/sigma(T)

The New Muon Collaboration

The muon-proton and muon-deuteron inclusive deep inelastic scattering cross sections were measured in the kinematic range 0.002 < x < 0.60 and 0.5 < Q2 < 75 GeV2 at incident muon e…

Variations on Minimal Gauge Mediated Supersymmetry Breaking

Michael Dine, Yosef Nir, Yuri Shirman

We study various modifications to the minimal models of gauge mediated supersymmetry breaking. We argue that, under reasonable assumptions, the structure of the messenger sector is…

Phenomenological Implications of Low Energy Supersymmetry Breaking

Savas Dimopoulos, Michael Dine, Stuart Raby +2

The experimental signatures for low energy supersymmetry breaking are presented. The lightest standard model superpartner is unstable and decays to its partner plus a Goldstino, $G…

What is the Scale of Supersymmetry Breaking

Michael Dine

For a long time, it has been widely assumed that if the underlying laws of nature are supersymmetric, supersymmetry is broken at a scale intermediate between the weak scale and the…

ALEPH Four-Jet Excess, and Parity Violation

P. H. Chankowski, D. Choudhoury, S. Pokorski

We review briefly the indications for some relatively light superpartners based on the ~ ~anomaly and discuss the dependence of the potential increase in on the assumpti…

Stability Bounds on Flavor-Violating Trilinear Soft Terms in the MSSM

J. A. Casas, S. Dimopoulos

The stability of the standard vacuum imposes constraints on flavor violating trilinear soft terms which are stronger than the laboratory bounds coming from the absence of neutral f…

Some Implications of Charge and Color Breaking in the MSSM

J. A. Casas, A. Lleyda, C. Muñoz

We examine some physically relevant implications of potentially dangerous charge and color breaking minima for supersymmetric models. First, we analyze the stability of the corresp…

Electroweak Symmetry Breaking and Physics Beyond the Standard Model

S. Dawson, H. Haber

In order to extend the Standard Model to TeV scale energies one must address two basic questions: (1) What is the complete description of the effective theory of fundamental partic…

Standard Model stability bounds for new physics within LHC reach

J. A. Casas, J. R. Espinosa, M. Quiros

We analyse the stability lower bounds on the Standard Model Higgs mass by carefully controlling the scale independence of the effective potential. We include resummed leading and n…

Problems for Supersymmetry Breaking by the Dilaton in Strings from Charge and Color Breaking

J. A. Casas, A. Lleyda, C. Muñoz

The general constraints on the parameter space of soft-breaking terms, in order to avoid dangerous charge and color breaking minima, are applied to the four-dimensional string scen…

Multiple Production of MSSM Neutral Higgs Bosons at High--Energy Colliders

A. Djouadi, H. E. Haber, P. M. Zerwas

The cross sections for the multiple production of the lightest neutral Higgs boson at high--energy colliders are presented in the framework of the Minimal Supersymmetric…

Experimental Signatures of Low Energy Gauge Mediated Supersymmetry Breaking

Savas Dimopoulos, Michael Dine, Stuart Raby +1

The experimental signatures for gauge mediated supersymmetry breaking are presented. The phenomenology associated with this class of models is distinctive since the gravitino is na…
