Focusing on the SO(10)-inspired model of leptogenesis, I will show that a class of solutions respects the restrictive strong thermal leptogenesis requirements.
When strong thermal leptogenesis is achieved, pre-existing flavoured B-L asymmetries produced by potential external mechanism are completely washed out during the same leptogenesis. As a consequence the amount of Baryon Asymmetry...

Production of a Z boson in association with b jets is a background in multiple searches for physics beyond the Standard Model, as well as in different searches for the Higgs boson. Furthermore, the measurement of the Z+b cross section can be used to measure PDFs and to test the predictions from theory. In this talk the measurement of the Z+b cross-section, using a sample of 2.1fb-1 of...

Many physics analyses with the ATLAS detector expect to have jets originating from b-quarks. Algorithms that allow to identify those jets are thus of great importance and it is crucial to understand their performance. In the final state of top quark pairs decays at least two b-jets are present. This b-enriched sample provides a perfect environment for calibration of b-tagging algorithms for...

I present a study of the forward energy flow in leptonically decaying W bosons using data of an integrated luminosity corresponding to 36 pb-1 of pp collision data at a centre-of-mass energy of 7 TeV. This data was recorded with the CMS detector during the 2010 running of the LHC. In this sample of W events, about 300 events with a rapidity gap of no significant energy deposit in one of the...

An updated measurement of the production cross section for pp -> ttbar at a center-of- mass energy of 7 TeV using data collected by the CMS detector at the Large Hadron Collider is presented. Top quark pair production candidate events are selected based one the presence of an isolated muon or electron of high transverse momentum, large missing transverse energy and hadronic jets. At least one...

We present new measurements of the single top quark production cross section in ppbar collisions at sqrt(s) = 1.96 TeV using data corresponding to 5.4 fb^−1 of integrated luminosity collected by the D0 detector at the Fermilab Tevatron Collider. The large mass of the top quark, close to the electroweak symmetry-breaking scale, makes it a good candidate for probing physics beyond the Standard...
