• ## POSSIBLE UNITARITY OF BLACK HOLE EVAPORATION

In the framework of finite-dimensional Fock space models, for a fixed given mean number of particles $\bar{n}_{k}$, blackbody-like or another, it is shown that there are, in the space $S$ of all pure states, a multi-dimensional subspace $s_{\bar{n}_{k}}$ of initial pure states and a corresponding multi-dimensional subspace $S_{\bar{n}_{k}}$ of final pure states yielding $\bar{n}_{k}$, which are mutually related by a unitary transformation.

• ## High-energy QCD: towards precision

In this talk, I will discuss some recent and ongoing theoretical progresses concerning Quantum Chromodynamics in the regime of high-energy scattering, or equivalently low Bjorken x, in which the nonlinearity of the gluon field dynamics is essential. I will focus mostly on advances in higher order computations, aiming at a precise description of this nonlinear regime.
