125. Effective Field Theory for the LHC and Dark Matter

Dr Florian Goertz (MPIK)

24/05/2018, 16:10

In this talk, I will discuss the EFT approach to LHC physics and Dark Matter searches regarding its validity and prospects to gain information on the underlying UV physics. In particular in the first case, correlations will be pointed out that allow to directly access the mass of new particles beyond collider reach, while in the second case, a new effective description will be presented that...

126. Minimal Dark Matter at Collider

Satoshi Shirai (Kavli IPMU)

A massive particle charged under the electroweak gauge symmetry is one of the best candidate of the dark matter and called "Minimal dark matter." In this talk, I will discuss new strategies for such a dark matter hunting at collider, using precision measurements of the standard processes.

127. Top-philic dark matter within and beyond the WIMP paradigm

Dr Jan Heisig (RWTH Aachen University)

24/05/2018, 16:50

We present a comprehensive analysis of top-philic Majorana dark matter that interacts via a colored t-channel mediator. Despite the simplicity of the model - introducing three parameters only - it provides an extremely rich phenomenology allowing to accommodate the relic density for a large range of coupling strengths spanning over six orders of magnitude. This model features all 'exceptional'...

128. Interplay between collider and dark matter searches in composite Higgs models

Dr Mikael Chala (DESY)

24/05/2018, 17:10

Many composite Higgs models predict the existence of vector-like quarks with masses outside the reach of the LHC, e.g. mQ > 2 TeV, in particular if these models contain a dark matter candidate. In such models the mass of the new resonances is bounded from above to satisfy the constraint from the observed relic density. We therefore develop new strategies to search for vector-like quarks at a...
