- Up until now the works regarding leptogenesis have discussed different mechanisms to explain the observed baryon asymmetry of the universe (BAU). The type-$II$ seesaw mechanism employing triplet scalars has been well studied in this context and the triplet vacuum expectation value (VEV) answering to the observed BAU is $(< 10^{-2} ~ GeV)$. On the contrary we are invoking an extended Georgi-Machacek type scenario, capable of generating BAU through leptogenesis while keeping the triplet VEV at a moderate range where it plays a nontrivial role in electroweak symmetry breaking (EWSB). In this study we have also considered the decaying scalar mass responsible for leptogenesis to be within a TeV and hence one can probe this possibility at the Large Hadron Collider (LHC) itself via different kinds of signature corresponding to different triplet VEV region.
