On the Question of a Possible Infrared Zero in the Beta Function of the Finite- Gross-Neveu Model
Gongjun Choi, Thomas Ryttov, Robert Shrock
We investigate whether the beta function of the finite- Gross-Neveu model, as calculated up to the four-loop level, exhibits evidence for an infrared zero. As part of our analys…
Adjoint SU(2) with Four Fermion Interactions
Jarno Rantaharju, Vincent Drach, Claudio Pica +1
Four fermion interactions appear in many models of Beyond Standard Model physics. In Technicolour and composite Higgs models Standard Model fermion masses can be generated by four…
Asymptotic Symmetries in de Sitter and Inflationary Spacetimes
Ricardo Z. Ferreira, McCullen Sandora, Martin S. Sloth
Soft gravitons produced by the expansion of de Sitter can be viewed as the Nambu-Goldstone bosons of spontaneously broken asymptotic symmetries of the de Sitter spacetime. We expli…
Vacuum alignment and radiatively induced Fermi scale
Tommi Alanne
We extend the discussion about vacuum misalignment by quantum corrections in models with composite pseudo-Goldstone Higgs boson to renormalisable models with elementary scalars. As…
Towards a Gravity Dual for the Large Scale Structure of the Universe
A. Kehagias, A. Riotto, M. S. Sloth
The dynamics of the large-scale structure of the universe enjoys at all scales, even in the highly non-linear regime, a Lifshitz symmetry during the matter-dominated period. In thi…
Sextet Model with Wilson Fermions
Martin Hansen, Claudio Pica
We present new results from our ongoing study of the SU(3) sextet model with two flavors in the two-index symmetric representation of the gauge group. In the simulations use unimpr…
EELT-HIRES the high-resolution spectrograph for the E-ELT
A. Marconi, P. Di Marcantonio, V. D'Odorico +70
The first generation of E-ELT instruments will include an optical-infrared High Resolution Spectrograph, conventionally indicated as EELT-HIRES, which will be capable of providing…
The new SOXS instrument for the ESO NTT
P. Schipani, R. Claudi, S. Campana +28
SOXS (Son Of X-Shooter) will be a unique spectroscopic facility for the ESO-NTT 3.5-m telescope in La Silla (Chile), able to cover the optical/NIR band (350-1750 nm). The design fo…
The Spectrum of Darkonium in the Sun
Chris Kouvaris, Kasper Langaeble, Niklas Grønlund Nielsen
Dark matter that gets captured in the Sun may form positronium-like bound states if it self-interacts via light dark photons. In this case, dark matter can either annihilate to dar…
Leading Gravitational Corrections and a Unified Universe
Alessandro Codello, Rajeev Kumar Jain
Leading order gravitational corrections to the Einstein-Hilbert action can lead to a consistent picture of the universe by unifying the epochs of inflation and dark energy in a sin…
Vector and Axial-vector resonances in composite models of the Higgs boson
Diogo Buarque Franzosi, Giacomo Cacciapaglia, Haiying Cai +2
We provide a non-linear realisation of composite Higgs models in the context of the SU(4)/Sp(4) symmetry breaking pattern, where the effective Lagrangian of the spin-0 and spin-1 r…
The Fine Structure Constant and Habitable Planets
McCullen Sandora
We use the existence of habitable planets to impose anthropic requirements on the fine structure constant, . To this effect, we present two considerations that restrict its valu…
Stationary configurations of the Standard Model Higgs potential: electroweak stability and rising inflection point
Giuseppe Iacobellis, Isabella Masina
We study the gauge-independent observables associated with two interesting stationary configurations of the Standard Model Higgs potential (extrapolated to high energy according to…
Gamma-ray triangles: a possible signature of asymmetric dark matter in indirect searches
Alejandro Ibarra, Sergio Lopez-Gehler, Emiliano Molinaro +1
We introduce a new type of gamma-ray spectral feature, which we denominate gamma-ray triangle. This spectral feature arises in scenarios where dark matter self-annihilates via a ch…
Asymmetric Dark Matter Models and the LHC Diphoton Excess
Mads T. Frandsen, Ian M. Shoemaker
The existence of dark matter (DM) and the origin of the baryon asymmetry are persistent indications that the SM is incomplete. More recently, the ATLAS and CMS experiments have obs…
Preheating in an Asymptotically Safe Quantum Field Theory
Ole Svendsen, Hossein Bazrafshan Moghaddam, Robert Brandenberger
We consider reheating in a class of asymptotically safe quantum field theories recently studied in \cite{Litim:2014uca, Litim:2015iea}. These theories allow for an inflationary pha…
A Unified Universe
Alessandro Codello, Rajeev Kumar Jain
We present a unified evolution of the universe from very early times until the present epoch by including both the leading local correction and the leading non-local term $R\…
Symmetries and composite dynamics for the 750 GeV diphoton excess
Diogo Buarque Franzosi, Mads T. Frandsen
The ATLAS and CMS experiments at LHC observe small excesses of diphoton events with invariant mass around 750 GeV. Here we study the possibility of nearly parity degenerate and vec…
