| Higgs compositeness in Sp(2N) gauge theories: a first-principle numerical study |
| Speaker: | Prof. Biagio Lucini (Swansea) |
| Abstract: | Compositeness provides an elegant fundamental mechanism for electroweak symmetry breaking. The essential ingredient is the existence of a new strong force that breaks chiral symmetry. Through the gauging of an appropriate SU(2) x U(1) subgroup of the residual symmetry group, the Nambu-Goldstone boson associated to the symmetry breaking becomes the Standard Model Higgs. The Sp(4) gauge theory with two Dirac fundamental flavours provides a candidate for the microscopic origin of composite Higgs models based on the SU(4)/Sp(4) coset of the chiral symmetry breaking, which has been advocated as having a phenomenology compatible with the Standard Model. We report on the first non-perturbative calculation from first principles of this theory. We present the first results for the spectrum of glueballs of the pure Sp(4) Yang-Mills theory, an EFT framework for the interpretation of the masses and |

| Time quasi-periodic solutions to nonlinear Klein-Gordon equations |
| Speaker: | Wei-Min Wang (Cergy-Pontoise) |
| Abstract: | We discuss time quasi-periodic solutions to nonlinear Klein-Gordon equations
on the torus in arbitrary dimensions. We will explain the result and the method,
which is based on Anderson localization and algebraic geometry.
