Combined limit on the production of a light gauge boson decaying into μ+μ− and π+π−

Combined limit on the production of a light gauge boson decaying into μ+μ− and π+π−

We searched for the μ+μ− decay of a light vector gauge boson, also known as dark photon, in the e+e−→μ+μ−γISR process by means of the Initial State Radiation (ISR) method. We used 1.93 fb−1 of data collected by the KLOE experiment at the DAΦNE ϕ-factory. No structures have been observed over the irr...
