Dear all,

we are happy to announce a new Focus Meeting on the theory of
fundamental interactions within the GGI TEA BREAKS' series.  
 It will take place via Zoom at https://infn-it.zoom.us/j/86182679816 

on 

WEDNESDAY MAY 19TH at 5:00 PM (CEST) 

and will be given by  

GIAN GIUDICE (CERN) & RICCARDO RATTAZZI  (EPFL - ÉCOLE POLYTECHNIQUE
FÉDÉRALE DE LAUSANNE)

They will talk about  "NATURALNESS AND THE FUTURE OF HIGH ENERGY
PHYSICS" 

ABSTRACT 

Naturalness arguments have been a powerful guiding principle for
physicists as they try to construct new theories. While considerations
based on simplicity and elegance have characterized the scientific
thought since very early times, numerical naturalness, as most clearly
formulated by 't Hooft and Wilson, has been especially influential in
the search for theories of fundamental interactions. When applied to our
current description of the microscopic world in terms of quantum field
theory, it leads to the apparent paradox of the smallness of the
electroweak scale and of the cosmological constant as compared to the
Planck scale. In this Focus Meeting, Gian Francesco Giudice and Riccardo
Rattazzi will review the concept of naturalness and its implications.
The seemingly convincing notions of naturalness and simplicity in
Effective Field Theory will be introduced and argued that they appear
mutually contradictory in both the SM and its natural extensions. This
state of things defines the Hierarchy Paradox. The hypotheses on which
the naturalness principle rests, the consequences of relaxing some of
these hypotheses, and the current attempts to develop new paradigms
beyond naturalness will then be discussed. 

Ample space for questions and discussion will be allocated at the end of
the TH Colloquium.  We have also created an online Q&A space for each
seminar. You can submit your question by filling the form [1]. The
answers will be published soon after.

Please forward this announcement to anyone who might be interested. 
We wait for your participation, 

The Organising Committee of the GGI Tea Breaks
