Probing quantum gravity using photons from a flare of the active galactic nucleus Markarian 501 observed by the MAGIC telescope

J. Albert et al., John Ellis, N. E. Mavromatos +3

We analyze the timing of photons observed by the MAGIC telescope during a flare of the active galactic nucleus Mkn 501 for a possible correlation with energy, as suggested by some…

Time-Dependent Vacuum Energy Induced by D-Particle Recoil

John Ellis, N. E. Mavromatos, D. V. Nanopoulos

We consider cosmology in the framework of a `material reference system' of D particles, including the effects of quantum recoil induced by closed-string probe particles. We find a…

Test of CPT Symmetry and Quantum Mechanics with Experimental data from CPLEAR

R. Adler, etal, J. Ellis +3

We use fits to recent published CPLEAR data on neutral kaon decays to and to constrain the CPT--violation parameters appearing in a formulation of the neutral kaon s…

X. Wang, J. Lopez, D. Nanopoulos

We compute the supersymmetric contribution to in a variety of supergravity models. We find $R^{\rm susy}_b\lsim0.0004$, which…

A Layman's guide to SUSY GUTs

J. Lopez, D. Nanopoulos, A. Zichichi

The determination of the most straightforward evidence for the existence of the Superworld requires a guide for non-experts (especially experimental physicists) for them to make th…

SUSY signals at HERA in the no-scale flipped SU(5) supergravity model

J. Lopez, D. Nanopoulos, X. Wang +1

Sparticle production and detection at HERA are studied within the recently proposed no-scale flipped supergravity model. Among the various reaction channels that could lead…

Sparticle and Higgs Production and Detection at LEPII in two Supergravity Models

J. Lopez, D. Nanopoulos, H. Pois +2

We study the most promising signals for supersymmetry at LEPII in the context of two well motivated supergravity models: (i) the minimal supergravity model including the st…
