Left-Right Model of Electroweak Interaction with one Bidoublet and one Doublet Higgs Fields

Damanik, Asan

Original · EN

We study the predictions of the left-right model of electroweak interaction based on SU(2)ₗ⊗ SU(2)ᵣ⊗ U(1) gauge group by using one bidoublet and one doublet Higgs fields. We can reproduce the low energy phenomenology of electroweak interaction by choosing the appropriate values of vacuum expectation values of Higgs fields. Leptons can obtain a mass via two scenarios, first via Higgs mechanism with non-zero 'hypercharge-like' I in Lagrangian density mass termms and put the Yukawa couplings Gₗ>>Gₗ*, and the second via Higgs mechanism followed by a seesaw mechanism without the requirement Gₗ>>Gₗ*.
