1 Radiative corrections in neutrino - deuterium disintegration

The radiative corrections of order α for the charged and neutral current neutrino-deuterium disintegration for energies relevant to the SNO experiment are evaluated. Particular attention is paid to the issue of the bremsstrahlung detection threshold. It is shown that the radiative corrections to the total cross section for the charged current reaction are independent of that threshold , as they...

Bubbling 1/2 BPS solutions of minimal six-dimensional supergravity

We continue our previous analysis (hep-th/0412043) of 1/2 BPS solutions to minimal 6d supergravity of bubbling form. We show that, by turning on an axion field in the T 2 torus reduction, the constraint F ∧ F , present in the case of an S × S reduction, is relaxed. We prove that the four-dimensional reduction to a bosonic field theory, whose content is the metric, a gauge field, two scalars and...

Radiative Corrections to Bremsstrahlung in Radiative Return

Radiating a photon from the initial state provides a useful tool for studying a range of low energy physics using a high-energy ee accelerator. Accurate results require careful calculation of the first order virtual photon corrections. We compare exact results for initial state radiative corrections, finding agreement to an order of 10 or better as a fraction of the Born cross-section for most ...

Radiative Corrections to E Radiative Corrections to E

We study the 1-loop corrections to the charged Higgs production both in the Minimal Supersymmetric Standard Model (MSSM) and in a more general type II two-Higgs-doublet model (THDM-II). We consider the full set of corrections (including soft photon contributions as well as box diagrams), and define a parametrization that allows a comparison between the two models. Besides the soft photon radiat...

Inflation with large supergravity corrections

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 inflation and supergravity. In this paper we show that it is possible to obtain a cosmologically flat direction, embedded within the minimal supersymmetric standard model, despite very large super-Hubble corrections. As an il...
