Compensation of B-L charge of matter with relic sneutrinos
Abstract
We consider massless gauge boson connected to B-L charge with and without compensation to complete the investigation of the gauging of B and L charges. Relic sneutrinos predicted by SUSY and composite models may compensate B-L charge of matter. As a consequence of the possible compensation mechanism we have shown that the available experimental data admit the range of the B-L interaction constant, 10-29 < αB-L < 10-12, in addition to αB-L < 10-49 obtained without compensation.
