11. Duality along the RG flow

Borut Bajc

28/08/2018 11:10

I will show an example of exact duality along the RG flow between the electric and magnetic versions of SQCD in D=4. In the vicinity of Nf=3Nc/2 the non-perturbative electric flow can be calculated in terms of the perturbative electric one.

5. Central charges and their constraints

Vladimir Prochazka

29/08/2018 10:00

I will introduce the idea of central charges and how they can imply constraints on UV/IR asymptotics of RG flows akin to 't Hooft anomalies. I will review some results on their monotonicity properties and the so-called a-theorem stating that the central charge 'a' decreases along the RG flow. I will then show how can central charges be computed in realistic theories and present examples. These...

7. Forging a link between quantum gravity and (beyond) Standard Model physics

Aaron Held

29/08/2018 14:30

Renormalization Group flows provide a link between Planck- and electroweak-scale physics, that could allow to test implications of quantum gravity at accessible energy scales [1]. Systematic truncations suggest the existence of a regime of asymptotically safe quantum gravity, in which gravity fluctuations induce a UV-completion of the matter sector. Within this scenario, the paradigm of...

8. The flavor puzzle and the Goldstone-Higgs

Simone Blasi

29/08/2018 15:15

We propose a unified model of scalar particles that addresses the flavour hierarchies, solves the strong CP problem, delivers a dark matter candidate,
and provides the trigger for electroweak symmetry breaking. Besides furnishing a unification of the recently proposed axiflavon with a Goldstone-Higgs sector, the scenario can also be seen as adding a model of flavour (and strong CP...

9. Dark Bound States of Vector-like fermions

Juri Smirnov

30/08/2018 10:00

I will discuss the possibility that dark matter in the universe is composed of bound states of fermions with vector-like masses. Those particles are well motivated theoretically in allow in particular to realise asymptotically safe extensions of the Standard Model. I will show that those fermions can form bound states due to a new gauge group, which confines above the temperature of the QCD...

10. Probing Baryogenesis through the Higgs Self-Coupling

Manuel Reichert

30/08/2018 10:45

The link between a modified Higgs self-coupling and the strong first-order phase transition necessary for baryogenesis is well explored for polynomial extensions of the Higgs potential. We broaden this argument beyond leading polynomial expansions of the Higgs potential to higher-order polynomial terms and to non-polynomial Higgs potentials with the use of the functional renormalization group....

14. Flavor Physics and Flavor Anomalies in Minimal Fundamental Partial Compositeness

Anders Thomsen

30/08/2018 15:15

I would like to present the paper of the same name, written in collaboration with F. Sannino, P. Stangl, and D. Straub. I will breifly review the Fundamental Partial Compositeness framework which is a realistic model for composite dynamics. I then present our analysis of the falvor physics in the minimal model. In particular the analysis finds parameter points that pass the current precision...

15. Large mass hierarchies in strongly coupled theories with multi-scale dynamics

Daniel Elander

31/08/2018 10:00

Strongly coupled theories exhibiting walking dynamics provide a scenario for beyond the Standard Model physics, in which electro-weak symmetry is broken dynamically and the large hierarchy between the electro-weak and Planck energy scales is naturally generated. Due to the spontaneous breaking of approximate scale invariance, a light dilaton can be expected to be present in the spectrum. In...

17. Probing the nature of Dark Matter at the ILC

Daniel Locke

31/08/2018 11:50

We analyse the potential of the proposed international linear collider to detect Dark Matter (DM) and determine its properties. In many models stability of Dark Matter particles D is ensured by conservation of a new quantum number referred to as D-parity. Our models also contain charged D-odd particles $D^{\pm}$ with the same spin as D. In this work, we study two minimal consistent models...
