Induced gravitational waves, metastable cosmic strings and primordial black holes in GUTs

Rinku Maji, Ahmad Moursy, Qaisar Shafi

We explore the cosmological and astrophysical implications of a realistic hybrid inflation model based on flipped $S U (5)$ . The model contains superheavy metastable cosmic strings a…

Kinetic Mixing, Proton Decay and Gravitational Waves in SO(10)

Rinku Maji, Qaisar Shafi

We present an $S O (10)$ model in which a dimension five operator induces kinetic mixing at the GUT scale between the abelian subgroups $U (1)_{B - L}$ and $U (1)_{R}$ . We discuss in this…

Topological structures, dark matter and gravitational waves in $E_{6}$

Rinku Maji, Qaisar Shafi, Amit Tiwari

We discuss the appearance of topological structures from the spontaneous breaking of $E_{6}$ to the Standard Model via its maximal subgroup $S O (10) \times U (1)_{ψ}$ . They include dumbb…

Quantum tunneling in the early universe: Stable magnetic monopoles from metastable cosmic strings

George Lazarides, Rinku Maji, Qaisar Shafi

We present a novel mechanism for producing topologically stable monopoles (TSMs) from the quantum mechanical decay of metastable cosmic strings in the early universe. In an $SO(10)…
