Muon g-2 and LHC phenomenology in the gauge symmetric model
In this paper, we consider phenomenology of a model with an
gauge symmetry. Since the muon couples to the gauge boson
(called boson), its contribution to the muon anomalous magnetic moment
(muon g-2) can account for the discrepancy between the standard model
prediction and the experimental measurements. On the other hand, the
boson does not interact with the electron and quarks, and hence there are no
strong constraints from collider experiments even if the boson mass is of
the order of the electroweak scale. We show an allowed region of a parameter
space in the symmetric model, taking into account consistency
with the electroweak precision measurements as well as the muon g-2. We study
the Large Hadron Collider (LHC) phenomenology, and show that the current and
future data would probe the interesting parameter space for this model.Comment: 26 pages, 12 figure
