About the rapidity and helicity distributions of the W bosons produced at LHC
W bosons are produced at LHC from a forward-backward symmetric initial state. Their decay to a charged lepton and a neutrino has a strong spin analysing power. The combination of these effects results in characteristic distributions of the pseudorapidity of the leptons decaying from W$^{+}$ and W$^{...

description | W bosons are produced at LHC from a forward-backward symmetric initial state. Their decay to a charged lepton and a neutrino has a strong spin analysing power. The combination of these effects results in characteristic distributions of the pseudorapidity of the leptons decaying from W$^{+}$ and W$^{−}$ of different helicity. This observation may open the possibility to measure precisely the W$^{+}$ and W$^{−}$ rapidity distributions for the two transverse polarisation states of W bosons produced at small transverse momentum. |
