Supersymmetric flat direction and NANOGrav 15 year data
Rinku Maji, Wan-Il Park
We show that, when connected with monopoles, the flat -flat direction breaking the local symmetry as an extension of the minimal supersymmetric standard model can b…
Inflation, superheavy metastable strings and gravitational waves in non-supersymmetric flipped SU(5)
George Lazarides, Rinku Maji, Ahmad Moursy +1
Motivated by the NANOGrav 15 year data and other recent investigations of stochastic gravitational background radiation based on pulsar timing arrays, we show how superheavy string…
Superheavy quasi-stable strings and walls bounded by strings in the light of NANOGrav 15 year data
George Lazarides, Rinku Maji, Qaisar Shafi
Composite topological structures such as superheavy "quasi-stable strings" (QSS) and "walls bounded by strings" (WBS) arise in realistic extensions of the Standard Model of high en…
Gravitational waves from walls bounded by strings in model of pseudo-Goldstone dark matter
Rinku Maji, Wan-Il Park, Qaisar Shafi
We explore the gravitational wave spectrum generated by string-wall structures in an () based scenario of pseudo-Goldstone boson dark matter (pGDM) particle. Thi…
