WZ production is an important process at the LHC because it probes the non-Abelian structureof electroweak interactions and it is a background process for many new physics searches. In the quest for new physics, polarization observables of the W and Z bosons can play an important role. They can be extracted from measurements and can be calculated using the Standard Model. In this contribution, we define fiducial polarization observables of the W and Z bosons and discuss the effects of next-to-leading order electroweak and QCD corrections in the Standard Model.
We present a study of the polarization observables of the $W$ and $Z$ bosons in the process $p p to W^pm Zto e^pm u_e mu^+mu^-$ at the 13 TeV Large Hadron Collider. The calculation is performed at next-to-leading order, including the full QCD correc
The pair production of a $W$ and a $Z$ boson at the LHC is an important process to study the triple-gauge boson couplings as well as to probe new physics that could arise in the gauge sector. In particular the leptonic channel $p p to W^pm Zto 3ell +
Accessing the polarization of weak bosons provides an important probe for the mechanism of electroweak symmetry breaking. Relying on the double-pole approximation and on the separation of polarizations at the amplitude level, we study WZ production a
We survey the expected polarization of the top produced in the decay of a scalar top quark, $tilde t rightarrow {tilde t}chi_i^0, i =1-2$. The phenomenology is quite interesting, since the expected polarization depends both on the mixing in the stop
The simplest extension of the Standard Model is to add a gauge singlet scalar, $S$: the singlet extended Standard Model. In the absence of a $Z_2$ symmetry $Srightarrow -S$ and if the new scalar is sufficiently heavy, this model can lead to resonant
