Models of string cosmology predict a stochastic background of gravitational waves with a spectrum that is strongly tilted towards high frequencies. I give simple approximate expressions for spectral densities of the cosmic background which can be directly compared with sensitivities of gravitational wave detectors.

In this lecture, we give a brief review of what theorists now know, understand, or guess about static and kinetic properties of quark–gluon plasma. A particular attention is payed to the problem of physical observability, i.e. the physical meaningfulness of various characteristics of QGP discussed in the literature.

We present a microscopic index formula for the degeneracy of dyons in four-dimensional N = 4 string theory. This counting formula is manifestly symmetric under the duality group, and its asymptotic growth reproduces the macroscopic Bekenstein-Hawking entropy. We give a derivation of this result in terms of the type II five-brane compactified on K3, by assuming that its fluctuations are describe...

We analyse the proton and deutron data on spin dependent asymmetry A 1 (x, Q 2) supposing the DIS structure functions g 1 (x, Q 2) and F 3 (x, Q 2) have the similar Q 2-dependence. As a result, we have obtained Γ p
