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.

We 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...

We present the first public implementation of antenna-based QCD initial- and final-state showers. 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...

We present a new approach to the realization of hard fixed-order corrections in predictions for the processes probed in high energy colliding hadron beam devices, with some emphasis on the LHC and the future FCC devices. We show that the usual unphysical divergence of such corrections as one approaches the soft limit is removed in our approach, so that
we would render the standard results to...

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,...

We present a detailed theoretical analysis of very rare, exclusive

focus is on the radiative decays Z -> M gamma, in which M is a

powers of Lambda_QCD/mV the decay amplitudes can be factorized into
convolutions of calculable hard-scattering coefficients with...

We extend the scaling behaviour observed in the inclusive charged hadron transverse momentum ($p_{T}$) distributions to the $p_{T}$ spectra of pions, kaons and protons produced in proton-proton ($pp$) collisions with center of mass energies ($\sqrt{s}$ ) at 0.9, 2.76 and 7 TeV. This scaling behaviour arises when a linear transformation, $p_{T} \rightarrow p_{T}/K$, is applied on the pion,...

Overview of the two component model for hadroproduction based on the recently published papers is presented. 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. Thus, charged hadron spectra produced in various interactions (pp, $\gamma$p,...

The 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...
