Fireballs and cannonballs confront the afterglow of GRB 991208
Shlomo Dado, Arnon Dar, Alvaro De Rujula
Galama et al. have recently reported their follow-up measurements of the radio afterglow (AG) of the Gamma Ray Burst (GRB) 991208, up to 293 days after burst, and their reanalysis…
Is the afterglow of Gamma Ray Burst 021004 unusual?
Shlomo Dado, Arnon Dar, Alvaro De Rujula
The bumpy light-curve of the bright optical afterglow (AG) of gamma ray burst (GRB) 021004, its spectral evolution and its radio emission have been claimed to be unusual. In the Ca…
Measurement of Neutral-Current Four-Fermion Production at LEP2
The OPAL collaboration
Four-fermion final states qqbar e+e- and qqbar mu+mu- from neutral-current interactions in e+e- collisions are studied in the OPAL detector at LEP at centre-of-mass energies from 1…
Measurement of the Cross-Section for the Process GammaGamma -> Ppbar at sqrt(s)_ee=183-189 GeV at LEP
The OPAL collaboration, G. Abbiendi
The exclusive production of proton-antiproton pairs in the collisions of two quasi-real photons had been studied using data taken at sqrt(s)_ee=183 GeV and 189 GeV with the OPAL de…
Search for Scalar Top and Scalar Bottom Quarks at LEP
The OPAL collaboration, G. Abbiendi
Searches for a scalar top quark and a scalar bottom quark have been performed using a data sample of 438 pb-1 at centre-of-mass energies of sqrt(s) = 192 - 209 GeV collected with t…
The supernova associated with GRB 020405
Shlomo Dado, Arnon Dar, Alvaro De Rujula
We use the very simple and successful Cannonball (CB) model of gamma ray bursts (GRBs) and their afterglows (AGs) to analyze the observations of the mildly extinct optical AG of th…
Search for Associated Production of Massive States Decaying into Two Photonsin e+e- Annihilations at sqrt(s) = 88-209 GeV
The OPAL collaboration, G. Abbiendi
A search is performed for production of short-lived particles in e+e- -> XY, with X -> gamma gamma and Y -> ffbar, for scalar X and scalar or vector Y. Model-independent limits in…
On the X-ray lines in the afterglows of GRBs
Shlomo Dado, Arnon Dar, Alvaro De Rujula
The observation of X-ray lines in the afterglow of GRB 011211 has been reported, and challenged. The lines were interpreted as blue-shifted X-rays characteristic of a set of photoi…
Search for Charged Excited Leptons in e+e- Collisions at sqrt(s) = 183-209 GeV
The OPAL collaboration
A search for charged excited leptons decaying into a lepton and photon has been performed using approximately 680 pb-1 of e+e- collision data collected by the OPAL detector at LEP…
Decay-mode independent searches for new scalar bosons with the OPAL detector at LEP
The OPAL collaboration, G. Abbiendi
This paper describes topological searches for neutral scalar bosons S0 produced in association with a Z0 boson via the Bjorken process e+e- -> S0Z0 at centre-of-mass energies of 91…
Measurement of the Charm structure Function F2c of the Photon at LEP
The OPAL collaboration, G. Abbiendi
The production of charm quarks is studied in deep-inelastic electron-photon scattering using data recorded by the OPAL detector at LEP at normal e+e- centre-of-mass energies from 1…
On the radio afterglow of gamma ray bursts
Shlomo Dado, Arnon Dar, A. De Rujula
We use the cannonball (CB) model of gamma ray bursts (GRBs) to predict the spectral and temporal behaviour of their radio afterglows (AGs). A single simple expression describes the…
