Implications of the diphoton excess on Left-Right models and gauge unification

Understand

The recent diphoton excess signal at an invariant mass of 750 GeV can be interpreted in the framework of left-right symmetric models with additional scalar singlets and vector-like fermions.

• We propose a minimal scenario for such a purpose.
• Extending the LRSM framework to include these new vector-like fermionic fields, on the other hand, results in interesting phenomenological implications for the LRSM fermion masses and mixing.
• Furthermore, existence of such vector-like fermions can also have interesting implications for baryogenesis and the dark matter sector.
