17. Tests of Lepton Flavour Universality with b-hadron decays at LHCb

Federico Betti (Universita e INFN, Bologna (IT))

10/05/2016, 16:30

parallel talk

Lepton Flavour Universality is enforced in the Standard Model by construction. Any Violation
of LFU would be a clear sign of new physics. Existing hints of non universality are
already present in the leptonic and semileptonic decays of B mesons. The semitauonic decays in particular,
are sensitive to contributions from non-standard-model-particles that preferentially couple to
the third...

61. Probes of CP-violation and rare decays with the ATLAS detector

Maria Smizanska (Lancaster University (GB))

10/05/2016, 16:45

parallel talk

Probes of CP-violation in decays of Beauty-strange meson and a high sensitivity measurements of the rare Bs decays with the ATLAS detector, using Run1 data are presented. Highlights on the expected performance for Run2 will be shown.

188. Heavy flavour production and spectroscopy at ATLAS

David Edwin Bertsche (University of Oklahoma (US))

10/05/2016, 17:00

parallel talk

ATLAS has a wide program to study the production properties of
conventional and exotic quarkonium, beauty, and charm bound states.
This presentation will cover the latest results on J/$\psi$, $\psi$(2s) and
$\Upsilon$ production at 7, 8, and 13 TeV, D meson and $\chi$(3872) production
with Run-1 data, B+ production at 13 TeV, and studies of associated
production of quarkonium with other...

16. Exotic spectroscopy at LHCb

Giovanni Cavallero (Universita e INFN Genova (IT))

10/05/2016, 17:15

parallel talk

The discovery of the first pentaquark states and the first unambiguous
determination of the Zc(4430) as a tetraquark state achieved at LHCb in
the last years have incredibly increased the interest for exotic
hadrons containing heavy quarks. An overview of the
recent LHCb results on quarkonium-like hadrons is presented, including a study of the Bs 𝜋± system

5. Fragmentation of Heavy Mesons and Quarkonia in Jets

Mr Lin Dai (PITT PACC)

10/05/2016, 17:30

parallel talk

We use e^+ e^- to 2 Jets and 3 Jets processes to study the fragmentation of B mesons and J/psi in identified jets with specific shapes (Angularities).

36. The electromagnetic decays of $B_c(2S)$

Guoli Wang (Harbin Institute of Technology)

10/05/2016, 17:45

parallel talk

I will introduce the eletromagnetic decays of the $B_c(2S)$ meson, which is recently observed by the ATLAS. In the calculation, the instantaneous Bethe-Salpeter method is used, and our results show that the branching ratio of eletromagnetic decays of this particle is about $10\%$ of the whole decay width.

135. The weak production and strong decays of D-wave charmonia

Dr Tianhong Wang (Harbin Institute of Technology)

10/05/2016, 18:00

parallel talk

We will talk about the production of D-wave charmonia ($2^{-+}$, $2^{--}$, $3^{--}$) in the weak decays of $B_c$ meson. The wave functions of the heavy mesons are achieved by solving the instantaneous Bethe-Salpeter equation. The three-gluon decay processes of these charmonia are also investigated.

152. Examining new physics signals in B=>D(*)tau nu

AMARJIT Soni (BNL)

Flavor

The claimed new physics signals in semi-leptonic B-decays are critically examined and the allowed parameter space in illustrative BSM model is studied.
