Systematic approach to thermal leptogenesis

In this work we study thermal leptogenesis using nonequilibrium quantum field theory. Starting from fundamental equations for correlators of the quantum fields we describe the steps necessary to obtain quantum-kinetic equations for quasiparticles. These ca ...

Lifting degeneracies in Higgs couplings using single top production in association with a Higgs boson

Andrea Thamm, Ennio Salvioni

Current Higgs data show an ambiguity in the value of the Yukawa couplings to quarks and leptons. Not so much because of still large uncertainties in the measurements but as the result of several almost degenerate minima in the coupling profile likelihood f ...

MosaicIA: an ImageJ/Fiji plugin for spatial pattern and interaction analysis

Aleksandra Radenovic, Arun Shivanandan

Background: Analyzing spatial distributions of objects in images is a fundamental task in many biological studies. The relative arrangement of a set of objects with respect to another set of objects contains information about potential interactions between ...

Transport properties of room-temperature ionic liquids from classical molecular dynamics

Nicola Marzari, Oliviero Andreussi

Room-temperature ionic liquids (RTILs) have attracted much attention in the scientific community in the past decade due their novel and highly customizable properties. Nonetheless, their high viscosities pose serious limitations to the use of RTILs in prac ...

Phosphorylation of 4E-BP1 in the Mammalian Brain Is Not Altered by LRRK2 Expression or Pathogenic Mutations

Liliane Glauser, Elpida Tsika, Darren Moore, Klodjan Stafa, Alzbeta Trancikova

Mutations in the leucine-rich repeat kinase 2 (LRRK2) gene are a common cause of autosomal dominant familial Parkinson's disease (PD). LRRK2 encodes a multi-domain protein containing GTPase and kinase enzymatic domains. Disease-associated mutations in LRRK ...

The other natural two Higgs doublet model

Riccardo Rattazzi, Andrea Wulzer, Jan Dalibor Mrazek

We characterize models where electroweak symmetry breaking is driven by two light Higgs doublets arising as pseudo-Nambu-Goldstone bosons of new dynamics above the weak scale. They represent the simplest natural two Higgs doublet alternative to supersymmet ...

Leptogenesis with TeV Scale Inverse Seesaw in SO(10)

Steve Blanchet

We discuss leptogenesis within a TeV-scale inverse seesaw model for neutrino masses where the seesaw structure is guaranteed by an SO(10) symmetry. Contrary to the TeV-scale type-I gauged seesaw, the constraints imposed by successful leptogenesis in these ...

Effects of heavy modes on vacuum stability in supersymmetric theories

Claudio Scrucca, Leonardo Brizi

We study the effects induced by heavy fields on the masses of light fields in supersymmetric theories, under the assumption that the heavy mass scale is much higher than the supersymmetry breaking scale. We show that the square-masses of light scalar field ...

Efficient evaluation of the accuracy of molecular quantum dynamics on an approximate analytical or interpolated ab initio potential energy surface

Jiri Vanicek, Tomas Zimmermann, Julien Ruppen

Ab initio electronic structure methods have reached a satisfactory accuracy for the calculation of static properties, but remain too expensive for quantum dynamical calculations. Recently, an efficient semiclassical method was proposed to evaluate the accu ...

Reconciling leptogenesis with observable μ → eγ rates

Steve Blanchet

We perform a detailed analysis of thermal leptogenesis in the framework of seesaw models which approximately conserve lepton number. These models are known to allow for large Yukawa couplings and a low seesaw scale in agreement with neutrino mass constrain ...
