6. Low-energy signals of dynamical electroweak symmetry breaking

Antonio Pich (University of Valencia)

9/8/15, 9:15 AM

Strongly-coupled electroweak scenarios are characterized by a spectrum of massive states at high scales. Using effective field theory techniques, we analyse their phenomenological implications at low energies. Integrating out the heavy particles, one gets a definite pattern of low-energy couplings in the resulting effective Lagrangian, which depends on the quantum numbers associated with the...

8. The case of a strongly interacting electroweak symmetry breaking sector at the LHC

Antonio Dobado (Universidad Complutense (ES))

9/8/15, 9:45 AM

The current data concerning the Higgs discovered at the LHC are compatible with having a strongly interacting electroweak symmetry breaking dynamics for the Higgs and the would-be Goldstone bosons. In this work we review this possibility and the consequences for LHC II.

41. Running vacuum energy in the expanding Universe: from inflation to our dark energy era

Prof. Joan Solà (Universitat de Barcelona)

9/8/15, 10:15 AM

An accelerated universe should naturally have a vacuum energy density determined by its dynamical curvature. The so-called cosmological constant is most likely a temporary description of a cosmic variable that has been drastically evolving from the early inflationary era to the present. In this talk, I will discuss a unified picture (in fact a class of models) of the expansion history of our...

23. Cosmological perturbations of the Higgs vev

Antonio Lopez Maroto

9/8/15, 10:45 AM

The standard Higgs mechanism for electroweak symmetry breaking predicts, apart from the existence of a scalar boson, the presence of a constant vacuum expectation value of the Higgs field. The Higgs vev, being determined by the effective potential, can however acquire space-time fluctuations from loop effects in inhomogeneous metric backgrounds. In this talk, we will present recent...
