We show that the N =0 theories on the self-dual D 3-branes of Type 0 string theory are in the class of the previously considered tadpole-free orbifolds of N =4 theory (although they have SO (6) global symmetry) and hence have vanishing beta function in the planar limit to all orders in 't Hooft...
Possible existence of new long range forces and their interaction strength are critically analyzed and reviewed.
We discuss theories in which the standard-model particles are localized on a brane embedded in space–time with large compact extra dimensions, whereas gravity propagates in the bulk. In addition to the ground state corresponding to a straight infinite brane, such theories admit a (one...
An estimate is presented of the leading radiative corrections to low energy electroweak precision measurements from strong nonresonant WW scattering at the TeV energy scale. The estimate is based on a novel representation of nonresonant scattering in terms of the exchange of an effective scalar...
We review recent papers on the anatomy of the confining string in the Abelian Higgs model with condensed Higgs field. The basic observation is that apart from the well known Abrikosov–Nielsen–Olesen strings of finite transverse size there exist infinitely thin topological strings. These...
Experimental results of the SPHINX Collaboration on studying proton diffractive production processes are presented. Evidences for new baryon states with masses ≳2 GeV were obtained in hyperon-kaon effective mass spectra in several reactions. Unusual properties of these massive states (small...
This paper discusses the importance of maintaining close working relations between scientists and their government. Several examples of this cooperation in the U.S. are presented to illustrate the benefits, as well as problems, that result from such cooperation, or lack thereof. These examples...
We briefly review the recent activity on neutrino masses and mixings which was prompted by the confirmation of neutrino oscillations by the Superkamiokande experiment.
