Abstract: We extend the Type I seesaw and suggest a $new$ seesaw mechanism to generateneutrino masses within the left-right symmetric theories where parity isspontaneously broken. We construct a next to minimal left-right symmetric modelwhere neutrino masses are determined irrespective of the B-L breaking scale andcall it the $new$ seesaw mechanism. In this scenario B-L scale can be very low.This makes B-L gauge boson and the quasi-Dirac $heavy$ leptons very light.These TeV scale particles could have large impact on lepton flavor and CPviolating processes. We also shed light on the phenomenological aspects of themodel within the reach of the LHC.
