Our guest speaker will be Professor Ignacio Cirac, pioneer in the field of quantum computation and its application in the field of information. Please reserve tickets via Eventbrite here to help with planning. Abstract: Hadronic matrix elements evaluated on the lattice can be converted to a continuum scheme such as MS using intermediate non-perturbative renormalisation schemes.
Abstract - An accurate understanding of binary black hole and neutron star systems is essential to interpret experimentally observed gravitational wave signals. Abstract: In this talk, I will review recent progress on the QCD phase diagram at non-vanishing baryon density from a particular family of toy models, namely four-Fermi theories.
Fundamental Particle Physics. Abstract: I describe recent large-scale grand-canonical numerical studies of the fermionic Hubbard Model, a model of electrons with nearest-neighbor hopping and on-site interactions, formulated on a honeycomb lattice. I will focus on results in String and Beyond the Standard Model Phenomenology.
Abstract: We analyze to which extent the KKLT proposal for the construction of de Sitter vacua in string theory is quantitatively controlled. Our focus is on the quality of the 10d supergravity approximation. As our main finding, we uncover and quantify an issue which one may want to call the "singular-bulk problem". In particular, we show that, requiring the curvature to be small in the conifold region, one is generically forced into a regime where the warp factor becomes negative in a significant part of the Calabi-Yau orientifold.
This implies true singularities, independent of the familiar, string-theoretically controlled singularities of this type in the vicinity of O-planes. Abstract: In this talk will be presented an overview of the phenomenology of BSM models featuring an extra heavy neutral resonance, usually called Z 1 -boson, and of Minimal Models, a simple extension of the SM that can account for dark matter and explain the existence of neutrino masses, which are generated radiatively.
