Presented by Dr. Katy CLOUGH on 3 Apr 2017 at 4:30 PM
In the paper arXiv:1609.04724, shortly to be published in JCAP, we studied, for the first time, collapse of axion stars numerically using the full non-linear Einstein equations of general relativity and the full non-perturbative cosine potential. We identified three regions of the parameter space: i) long-lived oscillating axion star solutions, with a base frequency modulated by self-interactions, ... More

We discuss fermionic dark matter in non-supersymmetric $E_6$ Grand Unification. The fundamental representation of $E_6$ contains, in addition to the standard model fermions, exotic fermions and we argue that one of them is a viable, interesting dark matter candidate. Its stability is guaranteed by a remnant discrete symmetry that originates when the $E_6$ gauge symmetry is broken spontaneously. We ... More

Many models of Higgs portal dark matter find themselves under pressure from increasingly tight direct detection constraints. In the framework of gauge field dark matter, we study how such bounds can be relaxed while retaining the thermal WIMP paradigm. When the hidden sector gauge symmetry is broken via the Higgs mechanism, the hidden sector generally contains unstable states which are lighter tha ... More

The annihilation of dark matter (DM) particles accumulated in the Sun could produce a flux of neutrinos, which is potentially detectable with neutrino detectors/telescopes and the DM elastic scattering cross section can be constrained. Although the process of DM capture in astrophysical objects like the Sun is commonly assumed to be due to interactions only with nucleons, there are scenarios in w ... More

Presented by Mr. Ernany ROSSI SCHMITZ on 3 Apr 2017 at 5:30 PM
In the framework of a 3−3−1 model with right-handed neutrinos and three scalar triplets we consider different spontaneous symmetry breaking patterns seeking for a non-linear realization of accidental symmetries of the model, which will produce physical Nambu-Goldstone (NG) bosons in the neutral scalar spectrum. We make a detailed study of the safety of the model concerning the NG boson emissio ... More

Presented by Mr. Jason VEATCH on 4 Apr 2017 at 4:30 PM
Abstract: With the discovery of the $m_h = 125$ GeV Higgs boson, a new pathway to testing BSM models with extended Higgs sectors was opened. Many models predict Higgs couplings to new particles, which motivate a variety of searches at the LHC. Furthermore, modifications to the SM could enhance the Higgs trilinear coupling, putting it within the range of present day experiments. This talk presen ... More

Following the LHC DM working group proposal, a simplified Dark Matter model approach has been widely adopted for the interpretation of LHC Run-II searches. In particular models with s-channel spin-1 and spin-0 mediators have been studied in detail. In this talk I will discuss the LHC phenomenology of the less explored spin-2 mediator scenario, presenting constraints on the model parameter space fr ... More

In a Quantum Field Theory with a time-dependent background time-translational symmetry is broken. We therefore expect renormalization to lead to time-dependent loop corrections. In my talk I will discuss the first order corrections to the power spectrum and the time-dependence that we observe.

Unitarity constraints on the scattering of longitudinal weak bosons can provide information about the spectra and effective description of Composite Higgs models. We use this information to construct realistic scenarios and study the potential of observing signals of strong vector boson scattering at the LHC and a 100 TeV collider.
