Inflation with large supergravity corrections
Anupam Mazumdar, Seshadri Nadathur, Philip Stephens
It is well known that large Hubble-induced supergravity corrections to the inflaton field can ruin the flatness of the potential, thus creating a tension between slow-roll inflatio…
A comparative study of small x Monte Carlos with and without QCD coherence effects
G. Chachamis, M. Deak, A. Sabio Vera +1
We compare two Monte Carlo implementations of resummation schemes for the description of parton evolution at small values of Bjorken x. One of them is based on the Balitsky-Fadin-K…
Fast Electroweak Symmetry Breaking and Cold Electroweak Baryogenesis
Kari Enqvist, Philip Stephens, Olli Taanila +1
We construct a model for delayed electroweak symmetry breaking that takes place in a cold Universe with T<<100 GeV and which proceeds by a fast quench rather than by a conventional…
Inflection point inflation within supersymmetry
Kari Enqvist, Anupam Mazumdar, Philip Stephens
We propose to address the fine tuning problem of inflection point inflation by the addition of extra vacuum energy that is present during inflation but disappears afterwards. We sh…
Inflation from a Non-Local Theory of Gravity
Philip Stephens
This paper studies the inflationary dynamics of a Non-Local Theory of gravity. This theory, based around derivatives of the Ricci Scalar in the Einstein-Hilbert action, was previou…
Probing Unified Origin of Dark Matter and Baryon Asymmetry at PAMELA/Fermi
Kazunori Kohri, Anupam Mazumdar, Narendra Sahu +1
We propose an unified model of dark matter and baryon asymmetry in a lepto-philic world above the electroweak scale. We provide an example where the inflaton decay products subsequ…
