CrossTalk Workshop: The Fate of Naturalness

Monday 12 Jun 2017, 09:00 → 20:30 Europe/Brussels

Jean Sacton seminar room (1G003) (Universe)

Naturalness is a central motivation for the study of physics beyond the Standard Model and it is one of the main open issue associated to electroweak symmetry breaking and to the nature of the Brout-Englert-Higgs boson. After the null results of LHC in finding new physics, it is crucial to assess if Naturalness is still a valid guiding principle and what are the most recent developments and proposals to address this outstanding open puzzle.
Please register timely to the event since the number of participants is limited.
The workshop will take place at the Vrije Universiteit Brussel (Pleinlaan 2, 1050 Brussels) in the Jean Sacton seminar room at the IIHE (1G003)
List of speakers:
Alessandro Strumia (Pisa University & CERN)
Steven Abel (Durham IPPP)
Christoph Englert (Glasgow University)
Diego Redigolo (Weizmann University)
Daniele Teresi (Universite Libre de Brussels)
Michael Spannowsky (Durham IPPP)

The workshop is supported by the Strategic Research Program HEP@VUB.
The workshop is part of a series HEP@VUB Crosstalk Workshops whose objective is to promote interdisciplinary activities across research groups in theoretical and experimental aspects of particle physics, astro-particle physics and high-energy astrophysics

Local Organizers: Alberto Mariotti and Alexander Sevrin

09:30 Welcome

1 Alessandro Strumia -- Nature natural again

LHC data are contradicting theoretical ideas that lead to expect new physics able of keeping the Higgs mass naturally small, such as supersymmetry. I will discuss the possibility that we might have over-interpreted quantum field theory, and present alternative views about what is going on.

2 Steve Abel -- Towards an asymptotically safe Standard Model

I discuss recent and ongoing work which aims to embed the Standard Model within an asymptotically safe framework of known gauge Yukawa theories. It is shown that radiative symmetry breaking generically occurs in these models in much the same way as it does in the MSSM. I discuss how a natural assignment of SM matter fields points towards an extended Pati-Salam like structure.
