Measurement of the transverse momentum distributions of W and Z bosons produced in $\\bar{p}p$ collisions at $\\sqrt{s} = 1.8$ TeV Open
We present measurements of the transverse momentum distribution of W and Z bosons produced in pbar p collisions at sqrt(s) = 1.8 TeV. The data were collected with the D0 detector at Fermilab during 1994-1996 Tevatron run. The results are i…

Prospects for searches for Higgs boson decays to dark photons at the ILC Open
An interesting model of dark matter involves a hidden sector decoupled from Standard Model (SM) fields except for some portal interaction. A concrete realization of this is the Hidden Abelian Higgs Model, which gives rise to decays of the …
