Diphoton excess from hidden U(1) gauge symmetry with large kinetic mixing

We show that the 750 GeV diphoton excess can be explained by introducing vector-like quarks and hidden fermions charged under a hidden U(1) gauge symmetry, which has a relatively large coupling constant as well as a significant kinetic mixing with U(1)Y. With the large kinetic mixing, the standard m...
