8 Dec 2002 | | Journal: | Phys.Rev.Lett. 91 (2003) 011801 | | Subject: | hep-ph | | Affiliation: | SINP, Kolkata), Ernest Ma (UC Riverside), Utpal Sarkar (PRL, Ahmedabad | | Abstract: | We propose a left-right model of quarks and leptons based on the gauge group $SU(3)_C imes SU(2)_L imes SU(2)_R imes U(1)_{B-L}$, where the scalar sector consists of only two doublets: (1,2,1,1) and (1,1,2,1). As a result, any fermion mass, whether it be Majorana or Dirac, must come from dimension-five operators. This allows us to have a common view of quark and lepton masses, including the smallness of Majorana neutrino masses as the consequence of a double seesaw mechanism. | | Source: | arXiv, hep-ph/0301041 | | Services: | Forum | Review | PDF | Favorites | |
