Various properties of some space like singularities in string theory will be discussed in the AdS/CFT holographic framework. Attempts to apply the diagnostic tools such as the study of  long time correlations and complexity, to these singularities, will be described.

The axial coupling of the nucleon, $g_A$, is a fundamental property of neutrons and protons. The long-range nuclear force between nucleons and the $\beta$-decay rate of a free neutron both depend on $g_A^2$. This coupling therefore underpins all of low-energy nuclear physics, controlling, for example, the primordial composition of the universe. While the value of... More »

Recent years have seen order of magnitude improvement in knowledge of quark mass parameters — these advances have been due largely to theoretical and computational advances in lattice QCD simulations. Present day calculations are able to obtain percent-level uncertainties; reducing these even further will be important for precision Higgs studies and BSM searches. I will... More »
