A bstractIdentifying the inflaton with a pseudo-Goldstone boson explains the flatness of its potential. Successful Goldstone Inflation should also be robust against UV corrections, such as from quantum gravity: in the language of the effective field theory this implies that all scales are sub-Planckian. In this paper we present scenarios which realise both requirements by examining the structure of Goldstone potentials arising from Coleman-Weinberg contributions. We focus on single-field models… 
Study in the noncanonical domain of Goldstone inflation
Recent observations of the Cosmic microwave background (CMB) indicate that a successful theory of cosmological inflation needs to have flat potential of the inflaton scalar field. Realising the
Linear inflation from quartic potential
A bstractWe show that if the inflaton has a non-minimal coupling to gravity and the Planck scale is dynamically generated, the results of Coleman-Weinberg inflation are confined in between two
Reheating with a composite Higgs boson
The flatness of the inflaton potential and lightness of the Higgs boson could have the common origin of the breaking of a global symmetry. This scenario provides a unified framework of Goldstone
Radiative plateau inflation
A bstractWe describe how monomial chaotic inflation becomes compatible with the latest CMB data thanks to radiative corrections producing a plateau. The interactions of the inflaton with other
Composite Higgs Models after Run 2
We assess the status of models in which Higgs is a composite pseudo-Nambu Goldstone boson, in the light of the latest 13 TeV Run 2 Higgs data. Drawing from the extensive Composite Higgs literature,

Trajectories with suppressed tensor-to-scalar ratio in Aligned Natural Inflation
In Aligned Natural Inflation, an alignment between different potential terms produces an inflaton excursion greater than the axion scales in the potential. We show that, starting from a general
GUT Physics in the Era of the LHC
Grand Unified Theories (GUTs) are one of the most interesting high-energy com- pletions of the Standard Model, because they provide a rich, powerful and elegant group-theoretical framework able to
Beyond Positivity Bounds and the Fate of Massive Gravity.
The combination of the theoretical bounds with the experimental constraints on the graviton mass implies that the latter is either ruled out or unable to describe gravitational phenomena, let alone to consistently implement the Vainshtein mechanism down to the relevant scales of fifth-force experiments, where general relativity has been successfully tested.


Pseudonatural Inflation
We study how to obtain a sufficiently flat inflaton potential that is natural from the particle physics point of view. Supersymmetry, which is broken during inflation, cannot protect the potential
An ignoble approach to large field inflation
We study an inflationary model developed by Kaloper and Sorbo, in which the inflaton is an axion with a sub-Planckian decay constant, whose potential is generated by mixing with a topological 4-form
Natural inflation with pseudo Nambu-Goldstone bosons.
We show that a pseudo-Nambu-Goldstone boson, with a potential of the form V(d) = A’[1 f cos(+/f)], can naturally give rise to an epoch of infiation in the early universe. Successful inflation can be
Curing the Ills of Higgsless models: The S parameter and unitarity
We consider various constraints on Higgsless models of electroweak symmetry breaking based on a bulk SU(2){sub L}xSU(2){sub R}xU(1){sub B-L} gauge group in warped space. First we show that the S
Monodromy in the CMB: Gravity Waves and String Inflation
We present a simple mechanism for obtaining large-field inflation, and hence a gravitational wave signature, from string theory compactified on twisted tori. For nil manifolds, we obtain a leading
The S-parameter in holographic technicolor models
We study the S parameter, considering especially its sign, in models of elec- troweak symmetry breaking (EWSB) in extra dimensions, with fermions localized near the UV brane. Such models are
Completing natural inflation
If the inflaton is a pseudo-scalar axion, the axion shift symmetry can protect the flatness of its potential from too large radiative corrections. This possibility, known as natural inflation,
The composite Higgs and light resonance connection
A bstractWeinberg sum-rules have been used in the past to successfully predict the electromagnetic contribution to the charged-pion mass as a function of the meson masses. Following the same approach

A model where inflation ends in a different way, due to a very rapid rolling (‘waterfall’) of a scalar field σ triggered by another scalar Field φ, which can be realized in a much greater variety of models than the new inflationary Universe scenario.
