Induced Gluon Radiation in a QCD Medium

R. Baier, Yu. L. Dokshitzer, S. Peigné +1

Soft gluon radiation induced by multiple scattering of a fast quark or gluon propagating through QCD matter is discussed. After revisiting the Landau-Pomeranchuk-Migdal effect in Q…

Supersymmetric Models with a Gauge Singlet and Non-Universal Soft Terms from Orbifold String Theory

Ph. Brax, U. Ellwanger, C. A. Savoy

The particle spectrum of the supersymmetric extension of the standard model with a gauge singlet is studied. Soft supersymmetry breaking terms are explicitly chosen to be non-unive…

Critical Analysis of Theoretical Estimates for $B$ to Light Meson Form Factors and the $B \to ψ K (K^{*})$ Data

R. Aleksan, A. Le Yaouanc, L. Oliver +2

We point out that current estimates of form factors fail to explain the non-leptonic decays $B \to ψ K (K^{*})$ and that the combination of data on the semi-leptonic decays $D \to…

Determination of the CP Violating Phase $γ$ by a Sum Over Common Decay Modes to $B_{s}$ and $B ˉ_{s}$

R. Aleksan, A. Le Yaouanc, L. Oliver +2

To help the difficult determination of the angle $γ$ of the unitarity triangle, Aleksan, Dunietz and Kayser have proposed the modes of the type $K^{-} D_{s}^{+}$ , common to $B_{s}$ and $\ba…

Diffractive Dissociation in Deep Inelastic Scattering at HERA

A. Capella, A. Kaidalov, C. Merino +1

The diffraction dissociation of virtual photons is considered in the framework of conventional Regge theory. It is shown that the recent HERA data on large rapidity gap events can…

Chiral Sum-Rules for $L_{(6)}^{W Z}$ Parameters and Application to $π^{0}, η, η^{'}$ Decays

B. Moussallam

The chiral expansion of the low energy processes $π^{0} \to γ γ$ and $η \to γ γ$ is reconsidered with particular emphasis on the question of the evaluation of the two low-energy parameters…

Parton Distributions in the Photon

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

We discuss in detail the photon structure function beyond the leading logarithm approximation. Of special concern is the factorization scheme and the hadronic input; we show how to…

Intermittency and Exotic Channels

A. Bialas, R. Peschanski

It is pointed out that accurate measurements of short-range two-particle correlations in like-charge $K π$ and in $π^{0} π^{0}$ channels should be very helpful in determining the ori…

Non-Debye Screening in Finite Temperature QCD

S. Peigné, S. M. H. Wong

We study the non-abelian, gauge invariant, screening potential between two charges in a quark-gluon plasma. Using Braaten and Pisarski resummed perturbation theory in temporal axia…

Nambu mass hierarchies in strings

P. Binetruy, E. Dudas

We show that a recent proposal by Nambu to generate a hierarchy among Yukawa couplings in the standard model may be easily implemented in superstring models. In such models, two of…

Structure functions and low x physics

A. Capella, A. Kaidalov, C. Merino +1

In the framework of conventional Regge theory we present a common description of total photon-proton cross-section and proton structure functions in the region $0 \leq Q^2 \leq 5 \…

Yukawa textures from an extra {\bf U(1)} symmetry?

E. Papageorgiu

The observed hierarchy of the quark and lepton masses and mixing angles has led to the parametrisation of the mass matrices in powers of the Cabibbo angle and a certain number of z…

Relativistic Effects in the Scalar Meson Dynamics

R. Kaminski, L. Lesniak, J. -P. Maillet

A separable potential formalism is used to describe the $π π$ and $K K$ interactions in the scalar-isoscalar states in the energy range from the $π π$ threshold up to 1.4 G…

The two-fermion relativistic wave equations of Constraint Theory in the Pauli-Schrödinger form

J. Mourad, H. Sazdjian

The two-fermion relativistic wave equations of Constraint Theory are reduced, after expressing the components of the $4 \times 4$ matrix wave function in terms of one of the $2\time…
