Supersymmetric hybrid inflation and current-carrying metastable cosmic strings in $S U (4)_{c} \times S U (2)_{L} \times U (1)_{R}$

Adeela Afzal, Maria Mehmood, Mansoor Ur Rehman +1

We construct a realistic supersymmetric model for superheavy metastable cosmic strings (CSs) that can be investigated in the current pulsar timing array (PTA) experiments. It is ba…

$I^¼$ -Hybrid Inflation and Metastable Cosmic Strings in $SU (3)_{c} \times SU (2)_{L} \times SU (2)_{R} \times U (1)_{B - L}$

Muhammad Nadeem Ahmad, Maria Mehmood, Mansoor Ur Rehman +1

We develop a scenario based on $I^¼$ -hybrid inflation within the framework of a left-right symmetric model defined by the gauge symmetry group $G_{3221} = SU(3)_c \times SU(2)_L \ti…
