Dr Pablo Goldenzweig (KIT)3/13/16, 8:30 AMExperimentOrdinaryThe ratio of the measured $\overline{B} \to D^{(\ast)} l \overline{\nu}$ decay rates for $l=\tau$ vs. $e,\mu$ from BaBar, Belle, and LHCb together show a significant deviation from the Standard Model. Belle's 2015 result of $\overline{B} \rightarrow D^{(\ast)} \tau^{-}\overline{\nu}_{\tau}$ with hadronic tagging and the current world average will be discussed. Furthermore, Belle's preliminary...Go to contribution page

Johannes Albrecht (TU Dortmund)3/13/16, 8:50 AMExperimentOrdinaryDuring Run 1 of the LHC, the LHCb experiment has collected a large sample of beauty-hadrons that corresponds to an integrated luminosity of 3.0 fb$^{-1}$ at $pp$ centre-of-mass energy of 7 and 8 TeV. This talk gives an overview of the rare decay measurements the LHCb collaboration performed using Run 1 data, with an emphasis on Flavour Changing Neutral Current processes of the type $b...Go to contribution page

Dr Lars Hofer (UB Barcelona)3/13/16, 9:15 AMTheoryOrdinaryRecently, the LHC has found several anomalies in exclusive semileptonic b --> s l l decays with a combined significance of more than 4 sigma. After a brief discussion of the hadronic uncertainties entering the theoretical prediction for the relevant decays, I present an interpretation of the data in terms of new physics. Based on model-independent global fits of the effective Wilson...Go to contribution page

Dr Sean Benson (CERN)3/13/16, 9:35 AMExperimentOrdinaryLatest LHCb measurements of $CP$ violation in the decays of b-hadrons are presented based on $pp$ collision data collected in Run 1, corresponding to an integrated luminosity of 1 fb$^{-1}$ at centre-of-mass energy 7 TeV and 2 fb$^{-1}$ at 8 TeV. New decays, $\Lambda_b\to \Lambda \pi^-K^+$ and $\Lambda_b\to \Lambda K^+K^-$, are identified and the associated $CP$ asymmetries are measured. The...Go to contribution page

Mr Alex Pearce (University of Manchester)3/13/16, 10:40 AMExperimentOrdinaryLHCb collected the world's largest sample of open charm decays during Run 1 of the Large Hadron Collider. This has permitted many precision measurements of charm mixing and $CP$ violation parameters, the most precise of which being $\Delta A_{CP}$, a measurement of the relative strength of direct, time-integrated $CP$ asymmetries between two singly-Cabibbo suppressed $D^{0}$ decays. This...Go to contribution page

Dr Sandro Palestini (CERN)3/13/16, 11:00 AMExperimentOrdinaryThe study of the rare decays $B^0_s \to \mu^+\mu^-$ and $B^0 \to \mu^+\mu^-$ has been performed using 25 fb$^{-1}$ of integrated luminosity collected with the ATLAS detector during LHC Run 1. The analysis and the results are presented.Go to contribution page

Dr Jeroen van Tilburg (Nikhef)3/13/16, 5:00 PMExperimentOrdinaryThe LHCb experiment has collected large samples of heavy flavoured hadrons during Run 1, corresponding to an integrated luminosity of 3.0 fb$^{-1}$ at $pp$ centre-of-mass energy of 7 and 8 TeV. Interesting results using semileptonic $B$ decays have been published, amongst which are a novel measurement of $|V_{ub}|$ and an enhanced branching ratio of semitauonic $B^0$ decays. The latter...Go to contribution page

Dr Malcolm John (University of Oxford)3/13/16, 5:20 PMExperimentOrdinaryLatest results will be presented from the analysis of open charm B-decays, sensitive to the CKM angle gamma, from the Run 1 LHCb dataset. This includes new results using the ADS, GLW and GGSZ techniques applied to B→DX decays. The talk will conclude with a discussion on the determination of gamma from these tree-level decays, as well as the associated hadronic parameters.Go to contribution page

Dr Giuseppe Ruggiero (CERN)3/13/16, 6:55 PMExperimentOrdinaryThe NA62 experiment at CERN SPS collected a large sample of charged kaon decays with a highly efficient trigger for decays into electrons in 2007 using the experimental setup of the earlier kaon experiment at CERN NA48/2. The kaon beam represents a source of tagged neutral pion decays in vacuum. A measurement of the electromagnetic transition form factor slope of the neutral pion in the...Go to contribution page

Karim Massri (University of Liverpool)3/13/16, 7:15 PMExperimentOrdinaryThe NA48/2 experiment at CERN collected a large sample of charged kaon decays into final states with multiple charged particles in 2003-2004. A new upper limit on the rate of the lepton number violating decay $K^{\pm} \rightarrow \pi^{\mp} \mu^{\pm} \mu^{\pm}$ obtained from this sample is reported: $8.6 \times 10^{-11}$ at 90% CL, which improves by more than an order of magnitude upon the...Go to contribution page

Dr Michele Lucente (Centre for Cosmology, Particle Physics and Phenomenology - CP3)3/13/16, 7:35 PMTheoryOrdinaryWe propose a minimal and motivated extension of the Standard Model characterised by an approximated lepton number conservation, which is able both to generate neutrino masses and to account for a successful baryogenesis via leptogenesis. The sterile fermions involved in the leptogenesis process have masses at the GeV scale. We determine the viable parameter space that complies with both the...Go to contribution page
