Exclusive processes with TOTEM and CT-PPS: results, perspectives and experimental challenges

Abstract: The latest results and the physics potential of the TOTEM experiment at the LHC will be presented. This include searches for glueballs and new physics together with CMS and a deeper understanding of elastic scattering. For LHC RUN-2, a joint CMS-TOTEM project (CT-PPS) has been approved to study exclusive particle production at the highest LHC luminosity. With the recent indication by the CMS and ATLAS experiments of a possible resonance in the 750 GeV mass region, the CT-PPS, initially designed to search for anomalous gauge boson quartic couplings, will give a relevant contribution in a possible confirmation and study of this new resonance. I will review the CT-PPS status and plans for 2016 LHC running.

In the second part of the seminar I will concentrate on the new detectors designed to precisely measure the time-of-flight of the scattered protons produced in such exclusive processes at medium and high luminosity to be able to reject pile-up. Timing detectors based on diamond sensors have been developed by TOTEM and will be used in the first phase of the CT-PPS project. I will summarize the detector development, performance and perspective for this promising technology.

On Higgs physics in the early universe

Abstract: I discuss the role of the Higgs field in the very early universe. Inflationary fluctuations of the Higgs field generically form a primordial Higgs condensate which might have left observable signatures. Stability of the SM vacuum against the fluctuations implies stringent constraints on Higgs couplings to spacetime curvature, or requires physics beyond SM. I review the stability constraints which may open interesting insights in probing new physics. I also discuss the decay of the primordial Higgs condensate which determines the duration of the early out-of-equilibrium epoch. If time allows, I comment also on the observational signatures of Higgs inflation.

Simplified models for DM searches at the LHC

Abstract: As the first results from Run II of the LHC are released, it is important to evaluate the ways in which we study DM at colliders. In the past we have used EFTs to constrain DM in a semi-model-independent way, but it is now clear that this approach has limitations. The community is moving full-speed into the usage of simplified models of dark matter, and it is important to approach them in a logical and consistent way so that we can learn as much as possible about the dark sector. Simplified models are designed to have fewer parameters than full, UV-complete models of dark matter, so that the full parameter space can be explored. At the same time, they are designed to still provide much the same phenomenology as full models, so that we don’t miss any potential signals. I will talk about some of the techniques and challenges we use to achieve these sometimes contradictory goals, and also how collider constraints fit into the broader search for dark matter.

Lattice Model of Ideal Walking

Abstract: We present preliminary studies of the SU(2) gauged NJL model with 2 flavors of fermions in the adjoint representation. The gauge model is infrared conformal and an additional NJL-type four fermion interaction, at large coupling, induces a chirally broken phase. In the symmetric phase the four fermion interaction is expected to influence the dynamics of the infrared fixed point and there may be a second order transition to the chirally broken phase. We study chiral symmetry breaking and the mass anomalous dimension at the infrared fixed point using the mode number of the Dirac operator.

Gravitational reheating after multi-field inflation

Abstract: It has recently been highlighted that details of the reheating process must be properly taken into account when constraining individual models of inflation with current high-precision CMB data, even in the case of single-field models. As inflation models with a non-minimal coupling between the gravity and inflaton sectors have recently attracted much attention, in this work we discuss reheating in this class of models, allowing for multiple inflaton fields. In such models, even in the absence of explicit interaction terms the inflaton sector can decay into matter as a result of its non-minimal coupling to gravity, thereby reheating the Universe gravitationally. Using the Bogoliubov approach we evaluate the gravitational decay rates of the inflaton sector, and analyse the reheating dynamics.
