Dear colleagues,

it is my pleasure to invite you to the seminar by prof. Tomislav Prokopec
from Institute for Theoretical Physics, Utrecht University, Netherlands.
The title of his talk is:

Conformal symmetry in the Standard Model and Gravity

Location: Department of Physics, F-201
Time: 14:00 on Wednesday, June 27th, 2018


----SEMINAR ABSTRACT--------------------------------------------------

I will discuss prospects of formulating simple extensions of the standard
model and gravity that exhibit local Weyl symmetry in the ultraviolet. The
principal advantage of such constructions is that they naturally address
the gauge and gravitational hierarchy problem. Furthermore,  I will argue
that Cartan-Einstein gravity provides a natural framework for conformal
symmetry, as this theory contains torsion vector which can be interpreted
as the Weyl vector. One of the main predictions of conformal theories of
gravity are torsion waves which can be in principle detected by
gravitational wave observatories. Finally, I will also discuss other
potential observable consequences of conformal symmetry arising from
electroweak symmetry breaking and inflation.
