Longevity of the quark-gluon plasma and the mixed phase from intensity interferometry of high energy photons

Dinesh K. Srivastava, Charles Gale

Two-photon intensity interferometry is shown to provide an accurate measurement of lifetime of quark-gluon plasma created in ultra-relativistic heavy ion collisions via the differe…

A Consistent Next-to-Leading-Order QCD Calculation of Hadronic Diffractive Scattering

J. R. Cudell, B. U. Nguyen

We calculate the order alpha_s^2 and order alpha_s^3 QCD contributions to colour-singlet exchange in the leading log s approximation. We implement the resulting amplitude at the ha…

Discrete Gauge Symmetries in Supersymmetric Grand Unified Models

M. De Montigny, M. Masip

We investigate the presence of discrete gauge symmetries in Grand Unification models based in $S O (10)$ and $E_{6}$ . These models include {\it flipped} and {\it unflipped} $S U (5)$ , $S…

Single Leptoquark Production

G. Belanger, D. London, H. Nadeau

The single production of leptoquarks in $e^{+} e^{-}$ , $e γ$ and $γ γ$ linear colliders is discussed. We show that these new particles could be seen in such machines even if their mass is…

Single Leptoquark Production at $e^{+} e^{-}$ and $γ γ$ Colliders

G. Belanger, D. London, H. Nadeau

We consider single production of leptoquarks (LQ's) at $e^{+} e^{-}$ and $γ γ$ colliders, for two values of the centre-of-mass energy, $s = 500$ GeV and 1 TeV. We find that LQ's whi…

Lepton pairs from thermal mesons

Charles Gale, Peter Lichard

We study the net dielectron production rates from an ensemble of thermal mesons, using an effective Lagrangian to model their interaction. The coupling between the electromagnetic…
