Generalized Born--Infeld Actions and Projective Cubic Curves

S. Ferrara, M. Porrati, A. Sagnotti +2

We investigate supersymmetric Born-Infeld Lagrangians with a second non-linearly realized supersymmetry. The resulting non-linear structure is more complex than the sq…

On sgoldstino-less supergravity models of inflation

Gianguido Dall'Agata, Fabio Zwirner

We go a step further in the search for a consistent and realistic supergravity model of large-field inflation by building a class of models with the following features: during slow…

New Higgs Inflation in a No-Scale Supersymmetric SU(5) GUT

John Ellis, Hong-Jian He, Zhong-Zhi Xianyu

Higgs inflation is attractive because it identifies the inflaton with the electroweak Higgs boson. In this work, we construct a new class of supersymmetric Higgs inflationary model…

Warped Dipole Completed, with a Tower of Higgs Bosons

Kaustubh Agashe, Aleksandr Azatov, Yanou Cui +2

In the context of warped extra-dimensional models which address both the Planck-weak- and flavor-hierarchies of the Standard Model (SM), it has been argued that certain observables…

Uniform gradient expansions

Massimo Giovannini

Cosmological singularities are often discussed by means of a gradient expansion that can also describe, during a quasi-de Sitter phase, the progressive suppression of curvature inh…

Instantaneous stochastic perturbation theory

Martin Lüscher

A form of stochastic perturbation theory is described, where the representative stochastic fields are generated instantaneously rather than through a Markov process. The correctnes…

Gauged R-symmetry and its anomalies in 4D N=1 supergravity and phenomenological implications

I. Antoniadis, D. M. Ghilencea, R. Knoops

We consider a class of models with gauged U(1)_R symmetry in 4D N=1 supergravity that have, at the classical level, a metastable ground state, an infinitesimally small (tunable) po…

The Quark Condensate in Multi-Flavour QCD - Planar Equivalence Confronting Lattice Simulations

Adi Armoni, Mikhail Shifman, Graham Shore +1

Planar equivalence between the large limits of Super Yang-Mills (SYM) theory and a variant of QCD with fermions in the antisymmetric representation is a powerful t…

Modelling hadronic interactions in HEP MC generators

Peter Skands

HEP event generators aim to describe high-energy collisions in full exclusive detail. They combine perturbative matrix elements and parton showers with dynamical models of less wel…

Radiation experience with the CMS pixel detector

Viktor Veszpremi

The CMS pixel detector is the innermost component of the CMS tracker occupying the region around the centre of CMS, where the LHC beams are crossed, between 4.3 cm and 30 cm in rad…
