Polarization Effects in the Search for Dark Vector Boson at Colliders

We argue that the search for dark vector boson through can determine the Lorentz structure of couplings with the detection of leptonic decays . We assume a general framework that the dark vector boson interacts with ordinary fermions through vector and axial-vector couplings. Taking , we study the c...

Description
Summary:We argue that the search for dark vector boson through can determine the Lorentz structure of couplings with the detection of leptonic decays . We assume a general framework that the dark vector boson interacts with ordinary fermions through vector and axial-vector couplings. Taking , we study the correlation between angle relative to beam direction in CM frame and angle relative to the boost direction of in rest frame. This correlation is useful for probing the Lorentz structure of couplings. We discuss the measurement of such correlation in Belle II detector.
