Axially symmetric particlelike solutions with the flux of a magnetic field in the non-Abelian Proca-Higgs theory

The Observation of Dark Photons in PHELEX with a Multi-Cathode Counter

“…It takes 3 years. Now one can only say that the effect observed during time span from 8-00 till 12-00 sideral time is on the level of about 0.005 Hz, that is., close to 2 % of the count rate of our counter with a cathode with the surface 0.26 m 2 . One can see from Fig.…”

“…We have developed a technique to search for dark photons with a multi-cathode counter [1] based on the detection of single electrons emitted from a metallic cathode during conversion of dark photons as particlelike solutions with the flux of magnetic or electric field [2,3] into single electrons emitted from the surface of cathode. The method has shown its efficiency in setting upper limits for the parameter of kinetic mixing [4].…”

“…It was discussed in [5] that if dark photons are polarized, i.e., vector of B or E -field of dark photons has a certain direction in stellar or solar frame, one can observe diurnal variations of the count rate of single electrons in the corresponding frame due to rotation of the Earth. Here we take just as a reference model the angular dependence of the effect from dark photons as cos 2 θ where θ is the angle between vector of B (E) field and the surface of the cathode. Because we still don't have a robust theory of dark photon, the real angular dependence can be different.…”
