High Energy Physics
Two-dimensional models provide for a very attractive playground being a theory imitating some of the main features of QCD. Those include the asymptotic freedom, mass gap, confinement, chiral symmetry breaking and others. Furthermore, there is a correspondence between the spectra of four-dimensional SQCD and N=(2,2) CP(N-1) sigma model which was discovered more than a decade ago. This correspondence was explained later when it was found that SQCD supports non-Abelian strings with confined monopoles. The kinks of the two-dimensional theory are the monopoles attached to the strings. Thus, analysis of two-dimensional sigma models gives a deeper insight into the four-dimensional SQCD, in particular, into its strong dynamics.

We study the BPS spectrum of the N=(2,2) CP(N-1) model with the Z_N-symmetric twisted mass terms. We focus on analysis of the "extra'' towers of states found previously and compare them to the states that can be identified in the quasiclassical domain. Exact analysis of the strong-coupling states shows that not all of them survive when passing to the weak-coupling domain. Some of the states decay on the curves of the marginal stability (CMS). Thus, most of the strong coupling states do not exist at weak coupling and cannot be classified quasiclassically. This result lifts to four dimensions. In terms of the four-dimensional theory, the "extra" states are the strong coupling dyons, while the quasiclassical bound states are the bound states of dyons and quarks.

Black holes are the elementary particles of gravity, the final state of sufficiently massive stars and of energetic collisions. With a forty-year long history, black hole physics is a fully-blossomed field which promises to embrace several branches of theoretical physics. Here I review the main developments in highly dynamical black holes with an emphasis on high energy black hole collisions and probes of particle physics via superradiance.

I discuss several recent efforts in relating string field theory calculations of BMN BMN BMN and BMN BMN BPS correlation functions to direct perturbative calculations and integrability-assisted methods. I review the next-to-leading order agreement between strings and perturbation theory in the SO(6) sector, a conjectured extension of the integrability techniques by Escobedo, Gromov, Sever, Vieira from the SU(2) to the full SO(6) sector and agreement with SFT and PT in it at the leading order; finally, I discuss the issue of equating exactly extremal and non-extremal correlators at NLO in the integrability-assisted calculation.

Physics is at a crossroad that leads either to Naturalness or the Multiverse. While the confirmation of gauge coupling unification in the early 90s gave a tremendous boost to naturalness and to low energy SUSY, the lack of evidence for new physics beyond the standard model at the LHC points to a paucity of new particles near the weak scale. This suggests that the weak scale is tuned and that supersymmetry, if present at all, is realized at higher energies. This points to Split SUSY, a framework motivated by the String Landscape. Fine-tuning electroweak symmetry breaking and the renormalization group evolution of the scalar masses constrains Split model building and I review the expectations at the LHC for the different possible Split SUSY particle spectra.
