Workshop on Multi-Higgs Models

Given LHC's Run 1, the ATLAS and CMS experiments at CERN could confidently announce the discovery of a scalar particle of 125 GeV consistent with the Standard Model Higgs boson. François Englert and Peter W. Higgs have been awarded the Nobel Prize in Physics 2013 for the development of the symmetry breaking mechanism and its signature particle.

But there is no fundamental reason why there should be only one Higgs. And Multi-Higgs models open up a wonderful new world:

the existence of charged scalars;
mixing between neutral scalar particles;
CP violation in the scalar sector;
vacua where charge conservation is broken;
substantial contributions to flavour-changing neutral currents;
and the possibility of spontaneous CP violation.

These features become extremely relevant in the search for new particles. Thus, Multi-Higgs models provide a very interesting testing ground for physics beyond the Standard Model in the electroweak symmetry breaking sector.

LHC's Run 2 has been scrutinizing the properties of the 125 GeV scalar to unprecedentend precision and probing whether there is indeed only one Higgs scalar or, perhaps, more. This is the ideal time to summarize the current status and future prospects.

This Workshop brings together those interested in the theory and phenomenology of Multi-Higgs models. The program is designed to include talks given by some of the leading experts in the field, and also ample time for discussions and collaboration betweeen researchers. A particular emphasis will be placed on identifying those features of the models testable in the future.

This Conference will take place in Lisboa, Portugal, at the Instituto Superior Técnico, on the 4th, 5th, 6th and 7th of September 2018. A map of the location may be found here. The closest subway ("Metro") stations are Saldanha and Alameda, on the Red Line. These are the directions to the conference room: (VA4) in Edifício de Cívil.

We would appreciate it if you could divulge the conference poster.
