Light-Gravitino Production at Hadron Colliders
Jaewan Kim, Jorge L. Lopez, D. V. Nanopoulos +2
We consider the production of gravitinos () in association with gluinos () or squarks () at hadron colliders, including the three main sub-process…
New (g-2)_μ Constraints on Light-Gravitino Models
T. Li, J. Lopez, D. Nanopoulos
We show that the gravitino contribution to (g-2)_μ is finite in many popular supergravity models, including no-scale supergravity and string and M-theory models. This contribution…
Compactifications of M-theory and their Phenomenological Consequences
T. Li, J. Lopez, D. Nanopoulos
We compactify the M-theory proposed by Horava and Witten on a Calabi-Yau manifold with boundary . A no-scale-like Kähler potential, the superpotential, and the gauge kinet…
M-theory Inspired No-scale Supergravity
T. Li, J. Lopez, D. Nanopoulos
We propose a supergravity model that contains elements recently shown to arise in the strongly-coupled limit of the heterotic string (M-theory), including a no-scal…
New Supersymmetric Contributions to
Jorge L. Lopez, D. V. Nanopoulos, Raghavan Rangarajan
We calculate the electroweak-like one-loop supersymmetric contributions to the rare and flavor-violating decay of the top quark into a charm quark and a gauge boson: , with…
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…
