| 英文摘要 | Searches are performed for both promptlike and long-lived dark photons, a', produced in proton-proton collisions at a center-of-mass energy of 13 tev, using a' -> mu(+)mu(-) decays and a data sample corresponding to an integrated luminosity of 1.6 fb(-1) collected with the lhcb detector. the promptlike a' search covers the mass range from near the dimuon threshold up to 70 gev, while the long-lived a' search is restricted to the low-mass region 214 < mo(a') < 350 mev. no evidence for a signal is found, and 90% confidence level exclusion limits are placed on the gamma-a' kinetic-mixing strength. the constraints placed on promptlike dark photons are the most stringent to date for the mass range 10.6 < m(a') < 70 gev, and are comparable to the best existing limits for m(a') < 0.5 gev. the search for long-lived dark photons is the first to achieve sensitivity using a displaced-vertex signature. |
