A critical phenomenological study of inclusive photon production in hadronic collisions

P. Aurenche, M. Fontannaz, J. Ph. Guillet +3

We discuss fixed target and ISR inclusive photon production and attempt a comparison between theory and experiments. The dependence of the theoretical predictions on the structure…

QCD '98: status of the power corrections

V. I. Zakharov

We review status of the power corrections in QCD. The topics include shape variables, unconventional 1/Q^2 corrections, tachyonic gluon mass as a fit parameter to the 1/Q^2 correct…

Identification of the glueballs and the scalar meson nonet of lowest mass

Peter Minkowski, Wolfgang Ochs

We discuss the theoretical expectations and phenomenological evidence for the lightest glueballs and the members of the meson nonet with quantum numbers J^PC=0^{++}. We reconsider…

Polarized top decay into polarized W: t(up)->W(up) + b at O(alpha_s)

M. Fischer, S. Groote, J. G. Körner +2

We consider the decay of a polarized top quark into a polarized W-boson plus a bottom quark, followed by the decay of the W-boson into a pair of leptons or quarks. The polar angle…

Fermion Mixing Renormalization and Gauge Invariance

P. Gambino, P. A. Grassi, F. Madricardo

We study the renormalization of the fermion mixing matrix in the Standard Model and derive the constraints that must be satisfied to respect gauge invariance to all orders. We demo…

Short-distance tachyonic gluon mass and 1/Q^2 corrections

K. G. Chetyrkin, Stephan Narison, V. I. Zakharov

We consider the assumption that a tachyonic gluon mass imitates short-distance nonperturbative physics of QCD. The phenomenological implications include modifications of the QCD su…
