Corso di laurea magistrale in Fisica

Gauge theories based on local invariance under a symplectic group provide an interesting and non-trivial generalization of those underlying the Standard Model of elementary particle physics, and have been proposed as viable candidates for New Physics scenarios, in which the Higgs boson is a bound state of a new type of strong interaction.
In this thesis project, to be carried out under joint supervision with Mattia Bruno from the University of Milano Bicocca, the properties of strongly coupled Sp(2N) gauge theories at finite temperature will be investigated by means of numerical calculations in the lattice regularization, neglecting the contribution of possible fermionic matter fields, and discussing the symmetry-breaking transition leading to a deconfined state of matter at high-temperature. The final goal of the project consists in determining the equation of state of such theories, and to compare its properties with those of the SU(3) gauge theory in quantum chromodynamics.
