Recent insights from string theory and supergravity on the macroscopic and the microscopic description of black hole entropy are discussed. To be published in the proceedings of the Symposium in honor of the 70th birthday of Julius Wess, München, 10-11 January, 2005.

Recent progress in application of higher order QCD calculations to jet and inclusive particle production in photon induced collisions is reviewed. Attention is paid to theoretical uncertainties of such calculations, particularly those coming from the choice of renormalization and factorization scales.

Properties and temperature behavior of π and σ bound states are studied in the framework of the nonlocal model with a separable interaction kernel based on the quark Dyson-Schwinger and the meson Bethe-Salpeter equations. Mπ(T ), fπ(T ), Mσ(T ) and Γσ→ππ(T ) are considered above and below the deconfinement and chiral restoration transitions.

I give a brief introduction to particle interactions based on representations of Poincare Lie algebra. This is later generalized to interactions based on representations of the supersymmetry Lie algebra. Globally supersymmetric models with internal symmetry and locally supersymmetric models leading to supergravity theories are presented. I also discuss higher dimensional supergravity theories a...
