A variety of vector boson measurements has been performed with Run 1 LHCb data, including inclusive Z/W cross-sections, the Z forward-backward asymmetry, Z plus charm, Z/W production with jets (including heavy flavor), and top production. Additionally, new inclusive Z/W cross-sections have been measured with Run 2 data. A summary of the most relevant results will be presented.

Dr Alexander Huss (ETH Zurich)04/08/2016, 14:45Strong Interactions and Hadron PhysicsOral PresentationWe present the complete calculation of the NNLO QCD corrections to the hadronic production of a charged lepton pair in association with a jet. Our results comprise various kinematical distributions that are of importance at the LHC and a significant reduction of the residual scale uncertainty is observed throughout. The corrections to differential distributions are not always uniform and imply...Go to contribution page

The shower kernels are $2\to 3$ antenna functions, which capture not only the collinear dynamics but also the leading soft (coherent) singularities of QCD matrix elements. We define the evolution measure to be inversely proportional to the leading poles, hence gluon emissions are evolved in a...Go to contribution page

Our understanding of the transition from partons to hadrons in QCD has been challenged in recent years. In particular for high-multiplicity minimum-bias events at the LHC, novel experimentation techniques have revealed tantalising indications of non-trivial and possibly collective phenomena. A new wave of model building efforts has ensued, including ideas of colour reconnections, colour ropes,...

The transverse momentum spectra, $d^2\sigma/(d\eta dp_T^2)$, of hadrons produced in high energy collisions can be decomposed into the two components: the exponential ("thermal") and the power ("hard") ones.

Dr David Wilson (for the Hadron Spectrum Collaboration)06/08/2016, 14:00Strong Interactions and Hadron PhysicsOral PresentationThe excited states in hadron physics are seen as resonances in the scattering of light stable states in QCD, like $\pi$, $K$ and $\eta$ mesons. Many excited states also decay into multiple final states, necessitating coupled-channel analyses. Recently it has become possible to obtain coupled-channel scattering amplitudes using lattice QCD. Using a large diverse basis of operators we are able...Go to contribution page
