Supersymmetry, Supergravity and R_b revisited in the light of LEP 2

J. Ellis, J. Lopez, D. Nanopoulos

A previous study of supersymmetric models has indicated that they are unlikely to make a large contribution to R_b. We revisit this analysis, taking into account the improved lower…

Single-photon signals at LEP in supersymmetric models with a light gravitino

J. Lopez, D. Nanopoulos, A. Zichichi

We study the single-photon signals expected at LEP in models with a very light gravitino. The dominant process is neutralino-gravitino production (e+e- -> chi+ G) with subsequent n…

Analysis of LEP Constraints on Supersymmetric Models with a Light Gravitino

J. Ellis, J. Lopez, D. Nanopoulos

We propose an analysis of LEP constraints on radiative neutralino decays into a light gravitino, based on the plane of the Higgs mixing parameter mu and the SU(2) gaugino mass M_2.…

Baryogenesis During Reheating in Natural Inflation and Comments on Spontaneous Baryogenesis

Alexandre Dolgov, Katherine Freese, Raghavan Rangarajan +1

We calculate the baryon asymmetry created by the decay of a pseudo Nambu-Goldstone boson whose interactions violate baryon number conservation. Our results are in disagreement with…

Supersymmetric photonic signals at LEP

J. Lopez, D. Nanopoulos, A. Zichichi

We explore and contrast the single-photon and diphoton signals expected at LEP 2, that arise from neutralino-gravitino (e^+ e^- -> chi + gravitino -> gamma + E_miss) and neutralino…

A supergravity explanation of the CDF event

J. Lopez, D. Nanopoulos

We present a unified no-scale supergravity model with a light gravitino that can naturally explain the observed event at CDF via right-handed selectron pair-production. The…

Enhanced Supersymmetric Corrections to Top-Quark Production at the Tevatron

J. Kim, J. Lopez, D. Nanopoulos +1

We calculate the one-loop supersymmetric electroweak-like and QCD-like corrections to the top-quark pair-production cross section at the Tevatron, including the important effects o…

Leptophobic in stringy flipped SU(5)

J. Lopez, D. Nanopoulos

We show that leptophobic gauge bosons occur naturally in flipped SU(5) and may shift in an interesting way without upsetting the good values of and . With…

Experimental constraints on a stringy SU(5)U(1) model

J. Lopez, D. Nanopoulos, A. Zichichi

We re-examine the phenomenological aspects of a recently proposed string-derived SU(5)U(1) one-parameter supergravity model, and explore the sensitivity of the model predic…
