In string theory the mass of such a dark photon cannot be predicted and experimental searches are indeed ongoing from very small mass scales, e.g. axion-like scales, to the highest scales at the LHC. More recently, dark photons on the MeV to GeV mass scale are at the focus of interest. This is due to the fact that Arkani-Hamed et al. [1] as well as others have suggested that such a dark photon could couple to dark matter, which would also explain quite a large number of astrophysical observations, such as e.g. the positron excess in the cosmic ray flux. Furthermore, it was realized that the presently seen deviation between the Standard Model prediction and the direct measurementof the anomalous magnetic moment of the muon, $(g−2)_\mu$, on the level of 3 to 4 standard deviations [2] could also be explained by a GeV-scale dark photon. The interaction strength of the dark photon with Standard Model matter is governed by the mechanism of kinetic mixing [3]. The coupling can be subsumed by an effective coupling constant $\epsilon$ and a vertex structure of a massive photon.}, month = {Jun}, date = {2013-06-24}, organization = {9th Patras Workshop on Axions, WIMPs and WISPs, Mainz (Germany), 24 Jun 2013 - 28 Jun 2013}, keywords = {Hypothetisches Teilchen (gnd)}, cin = {L}, cid = {I:(DE-H253)L-20120731}, pnm = {899 - ohne Topic (POF3-899)}, pid = {G:(DE-HGF)POF3-899}, experiment = {EXP:(DE-MLZ)NOSPEC-20140101}, typ = {PUB:(DE-HGF)29 / PUB:(DE-HGF)8 / PUB:(DE-HGF)7}, doi = {10.3204/DESY-PROC-2013-04/denig_achim}, url = {https://bib-pubdb1.desy.de/record/408323}, }
