The lightness of the Standard Model (SM) neutrinos could be understood if their masses were to be generated by new physics at a high scale. through the so-called seesaw mechanism involving heavy fermion singlets. We consider a novel scenario where the new physics violates baryon minus lepton number by only a small amount resulting in both heavy fermion singlets and the SM neutrinos to... https://www.perfumetank.com/product-category/household-towels/
