### Higgsed Gauge-flation

- PhysicsJournal of High Energy Physics
- 2017

We study a variant of Gauge-flation where the gauge symmetry is spontaneously broken by a Higgs sector. We work in the Stueckelberg limit and demonstrate that the dynamics remain (catastrophically)…

We study a variant of Gauge-flation where the gauge symmetry is spontaneously broken by a Higgs sector. We work in the Stueckelberg limit and demonstrate that the dynamics remain (catastrophically)…

### Constant-roll (quasi-)linear inflation

- Physics
- 2017

In constant-roll inflation, the scalar field that drives the accelerated expansion of the Universe is rolling down its potential at a constant rate. Within this framework, we highlight the relations…

### Constant‐Roll Inflation in the Generalized SU(2) Proca Theory

- MathematicsAnnalen der Physik
- 2022

The generalized SU(2) Proca theory (GSU2P) is a variant of the well known generalized Proca theory where the vector field belongs to the Lie algebra of the SU(2) group of global transformations under…

### Inflation driven by massive vector fields with derivative self-interactions

- MathematicsInternational Journal of Modern Physics D
- 2019

Inspired by the Generalized Proca Theory, we study a vector–tensor model of inflation with massive vector fields and derivative self-interactions. The action under consideration contains a usual…

### Bounds on the Horndeski gauge-gravity coupling

- PhysicsJournal of Cosmology and Astroparticle Physics
- 2020

The Horndeski gauge-gravity coupling is the leading non-minimal interaction between gravity and gauge bosons, and it preserves all the symmetries and the number of physical degrees of freedom of the…

### Inflation with mixed helicities and its observational imprint on CMB

- PhysicsPhysical Review D
- 2019

In the framework of effective field theories with prominent helicity-0 and helicity-1 fields coupled to each other via a dimension-3 operator, we study the dynamics of inflation driven by the…

### Non-trivial gravitational waves and structure formation phenomenology from dark energy

- PhysicsJournal of Cosmology and Astroparticle Physics
- 2018

The detection of the GW170817/GRB170817A event improved the constraints on the propagation speed of gravitational waves, thus placing possible variations caused by dark energy under restraint. For…

### Beyond standard models in cosmology (In French)

- Physics
- 2017

The current description of fundamental interactions is based on two theories with the status of standard models. The electromagnetic and nuclear interactions are described at a quantum level by the…

### Yang-Mills Condensates in Cosmology

- Physics
- 2012

We discuss homogeneous and isotropic cosmological models driven by SU(2) gauge fields in the framework of Einstein gravity. There exists a Yang-Mills field configuration, parametrized by a single…

### Cosmological models with Yang-Mills fields

- Physics
- 2010

We discuss cosmological models involving homogeneous and isotropic Yang-Mills (YM) fields. Such models were proposed recently as an alternative to scalar models of cosmic acceleration. There exists a…

### Non-Abelian Gauge Field Inflation

- Physics
- 2011

In [arXiv:1102.1513] we introduced an inflationary scenario, Non-Abelian Gauge Field Inflation or gauge-flation for short, in which slow-roll inflation is driven by non-Abelian gauge field minimally…

### Galileons with Gauge Symmetries

- Physics
- 2012

Galileon models arise in certain braneworld scenarios as modifications to General Relativity, and are also interesting as field theories in their own right. We show how the galileon model can be…

### Non-Abelian Einstein-Born-Infeld-Dilaton cosmology

- Physics
- 2006

The non-Abelian Einstein-Born-Infeld-dilaton theory, which rules the dynamics of tensor-scalar gravitation coupled to a $su(2)$-valued gauge field ruled by Born-Infeld Lagrangian, is studied in a…

### NONMINIMAL ISOTROPIC COSMOLOGICAL MODEL WITH YANG–MILLS AND HIGGS FIELDS

- Physics
- 2008

We establish a nonminimal Einstein–Yang–Mills–Higgs model, which contains six coupling parameters. The first three parameters relate to the nonminimal coupling of a non-Abelian gauge field and a…

### Natural inflation on a steep potential with classical non-Abelian gauge fields.

- PhysicsPhysical review letters
- 2012

It is found that inflation continues until the axionic potential vanishes, and for sub-Planckian axion decay constants vanishingly small tensor to scalar ratios are predicted, a direct consequence of the Lyth bound.

### Natural inflation with pseudo Nambu-Goldstone bosons.

- PhysicsPhysical review letters
- 1990

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…

### Cosmology with a nonminimally coupled Yang-Mills field

- Physics
- 2015

We discuss a cosmological model with a homogeneous and isotropic Yang-Mills field nonminimally coupled to gravity through an effective mass term. In this model conformal symmetry is violated, which…
