Neutrino mass hierarchy and matter effects

Alexei Yu. Smirnov

Matter effects modify the mixing and the effective masses of neutrinos in a way which depends on the neutrino mass hierarchy. Consequently, for normal and inverted hierarchies the…

Computation of multi-leg amplitudes with NJet

Simon Badger, Benedikt Biedermann, Peter Uwer +1

In these proceedings we report our progress in the development of the publicly available C++ library NJet for accurate calculations of high-multiplicity one-loop amplitudes. As a p…

NLO QCD corrections to WWbb production and top quark observables

Johannes Schlenk, Gudrun Heinrich, Jan Winter

We present the NLO QCD corrections to the production of a W+W- pair and two b-jets, including the leptonic decays of the W bosons. Contributions from singly resonant and non-resona…

Two-loop applications of the program SecDec

Sophia Borowka, Gudrun Heinrich

SecDec is a program which can be used for the factorisation of poles and subsequent numerical evaluation of multi-loop integrals, in particular massive two-loop integrals. We show…

Baryon Asymmetry, Dark Matter and Local Baryon Number

Pavel Fileviez Perez, Hiren H. Patel

We propose a new mechanism to understand the relation between the baryon and dark matter asymmetries in the universe in theories where the baryon number is a local symmetry. In the…

Searching for the squark flavor mixing in CP violations of Bs -> K+ K- and K0bar K0 decays

Atsushi Hayakawa, Yusuke Shimizu, Morimitsu Tanimoto +1

We study CP violations in the B_s-> K+K- and Bs->K0K0 decays in order to find the contribution of the supersymmetry, which comes from the gluino-squark mediated flavor changing cur…
