Abstract: I will report on how some versions of the 2-Higgs doublet model (2HDM) are doing when confronted with the LHC data. I will also discuss some interesting limits of 2HDMs and in particular the case of degenerate scalars. Finally I will discuss how the LHC results help us to sleep safe at night.
This is an introductory course on quantum field theory, focusing on particle physics and relativistic applications, though some of the tools may also be applied to condensed matter systems. The level will be aimed at 3rd/4th year Physics students, so there will be revision lectures to set the notation and background on quantum mechanics and special relativity.
Abstract: In this talk we discuss the quantum theory of a scalar field on LQC Bianchi I geometry. By focusing on single modes of the scalar field, we show that, evolution of the quantum field on the background quantum space-time leads to a classical effective geometry emerging whose components depend on the quantum geometrical operators.
The first meeting of the Numerical Relativity and High Energy Physics Network took place at Aveiro University, from 9-13 July 2012. This meeting brought together researchers from Brazil, Italy, Portugal, Spain and the USA, to discuss the state of the art in relativistic gravity and its application in various contexts, ranging from astrophysics to particle physics, using both anaytical and numerical techniques.
Abstract: In this talk I will discuss Supersymmetric Grand Unification Theories (SUSY GUTs), focussing on the standard SU(5), SO(10) and E6 candidates. A short review of the Standard Model of Particle Physics is given as well as the main motivations for SUSY GUTs.
Abstract: I will describe a top-down holographic model of strongly-interacting fermions in 2+1 dimensions using D3 and D7 branes. The black hole embeddings of the D7-branes correspond to metallic states, while the Minkowski embedding represents a quantum Hall fluid at quantized fractional filling fraction.
Abstract: Recently we have investigated the wave equation of a massive vector boson, which is governed by Proca field, in the D-dimensional Schwarzschild background. Because the mass term introduce a coupling between two physical degrees of freedom, we have to solve s set of coupled ordinary differential equations.
Abstract: It is well known that D-dimensional vacuum gravity with D-2 commuting Killing vectors is integrable. For such theories a solution generating technique has been available since it was first presented by Belinski and Zakharov in 1978.
The European Commission Research Executive Agency approved an International Research Staff Exchange Scheme (IRSES) Marie Curie action on "Numerical Relativity and High Energy Physics" (NRHEP), within the FP7 People Programme.
Our group coordinated the "Numerical Relativity and High Energy Physics" IRSES network (2012-2015). Here is a list of the global network meetings organized:
