Symmetry transformations in Batalin-Vilkovisky formalism

This short note is closely related to Sen-Zwiebach paper on gauge transformations in Batalin-Vilkovisky theory (hep-th 9309027). We formulate some conditions of physical equivalence of solutions to the quantum master equation and use these conditions to give a very transparent analysis of symmetry transformations in BV-approach. We prove that in some sense every quantum observable (i.e. every even function $H$ obeying $\Delta_{\rho}(He^S)=0$) determines a symmetry of the theory with the action functional $S$ satisfying quantum master equation $\Delta_{\rho}e^S=0$ \endComment: 3 page

Some simple predictions from E_{11} symmetry

The simplest consequences of the common E_{11} symmetry of the eleven dimensional, IIA and IIB theories are derived and are shown to imply the known relations between these three theories.Comment: plain tex, 14 page

Proton Emission Times in Spectator Fragmentation

Proton-proton correlations from spectator decays following Au + Au collisions at 1000 AMeV have been measured with an highly efficient detector hodoscope. The constructed correlation functions indicate a moderate expansion and low breakup densities similar to assumptions made in statistical multifragmentation models. In agreement with a volume breakup rather short time scales were deduced employing directional cuts in proton-proton correlations.Comment: 4 pages, with 2 included figures; To appear in the proceedings of the Bologna 2000 conference; Also available from http://www-kp3.gsi.de/www/kp3/aladin_publications.htm
