Description
[This talk will be on JHEP 1801 (2018) 011 by Soumita Pramanick and Amitava Raychaudhuri]
Three-higgs doublet model in $A4$ symmetric framework will be discussed.
It was observed that if we consider three $SU(2)_L$ doublet scalars forming a triplet under
$A4$ symmetry, alignment follows for four global minima configurations of the vacuum expectation values (vevs) naturally owing to the $A4$ symmetry. No fine-tuning was needed.
Positivity and unitarity conditions were satisfied.
