Scale invariance and strong dynamics as the origin of inflation and the Planck mass / Yamada, Masatoshi (speaker)
Classical scale invariance represents a promising framework for model building beyond the Standard Model. However, once coupled to gravity, any scale-invariant microscopic model requires an explanation for the origin of the Planck scale. [...]

Resurrecting Quadratic Inflation in No-Scale Supergravity in Light of BICEP2 / Ellis, John (CERN ; King's Coll. London) ; García, Marcos A.G. (Minnesota U.) ; Nanopoulos, Dimitri V. (Athens Academy ; HARC, Woodlands ; Texas A-M) ; Olive, Keith A. (Minnesota U.)
The magnitude of primordial tensor perturbations reported by the BICEP2 experiment is consistent with simple models of chaotic inflation driven by a single scalar field with a power-law potential \propto \phi^n: n \simeq 2, in contrast to the WMAP and Planck results, which favored models resembling the Starobinsky R + R^2 model if running of the scalar spectral index could be neglected. While models of inflation with a quadratic potential may be constructed in simple N=1 supergravity, these constructions are more challenging in no-scale supergravity. [...]

On the preheating in a scale invariant UV extension of Higgs inflation / Kamada, Kohei (speaker)
Higgs inflation with the nonminimal coupling to gravity \xi H^2 R is the unique model to realize inflation driven by the Standard Model Higgs field in a classically scale invariant way. However, the reheating in that model is not understood well yet. In particular, in the so-called “non-critical” regime, it turned out that there are violent instabilities in the longitudinal mode at very high energy scales. [...]

Spontaneous Breaking of Restricted Weyl Symmetry in Pure R^2 Gravity / Edery, Ariel (speaker)
Recent work has shown that pure R^2 gravity (i.e. R^2 gravity with no extra R term) has a symmetry that is larger than scale symmetry and smaller than full Weyl symmetry. [...]

Origin and Phenomenology of Weak-Doublet Spin-1 Bosons / Chizhov, M.V. (Sofiya U. ; Dubna, JINR) ; Dvali, Gia (CERN ; New York U., CCPP ; New York U. ; Munich, Max Planck Inst.)
We study phenomenological consequences of the Standard Model extension by the new spin-1 fields with the internal quantum numbers of the electroweak Higgs doublets. We show, that there are at least three different classes of theories, all motivated by the hierarchy problem, which predict appearance of such vector weak-doublets not far from the weak scale. [...]

Building Models of Inflation in No-Scale Supergravity / Ellis, John (King's Coll. London ; CERN ; NICPB, Tallinn) ; Garcia, Marcos A.G. (Madrid, IFT) ; Nagata, Natsumi (Tokyo U.) ; Nanopoulos Dimitri V. (TAMU, College Station ; HARC, Woodlands ; Athens Academy) ; Olive, Keith A. (Minnesota U.) ; Verner, Sarunas (Minnesota U.)
After reviewing the motivations for cosmological inflation formulated in the formalism of supersymmetry, we argue that the appropriate framework is that of no-scale supergravity. We then show how to construct within this framework inflationary models whose predictions for the tilt in the spectrum of scalar perturbations, $n_s$, and the ratio, $r$, of tensor and scalar perturbations coincide with those of the $R + R^2$ model of inflation proposed by Starobinsky.

Starobinsky-like Inflationary Models as Avatars of No-Scale Supergravity / Ellis, John (King's Coll. London ; CERN) ; Nanopoulos, Dimitri V. (Texas A-M ; HARC, Woodlands ; Athens Academy) ; Olive, Keith A. (Minnesota U., Theor. Phys. Inst.)
Models of cosmological inflation resembling the Starobinsky R + R^2 model emerge naturally among the effective potentials derived from no-scale SU(N,1)/SU(N) x U(1) supergravity when N > 1. We display several examples in the SU(2,1)/SU(2) x U(1) case, in which the inflaton may be identified with either a modulus field or a matter field. [...]
