Revisit a realistic intersecting D6-brane with modified soft SUSY terms
Imtiaz Khan, Waqas Ahmed, Tianjun Li +1
Because there are a few typos in the supersymmetry breaking sfermion masses and trilinear soft term, regarding the current Large Hadron Collider (LHC) and dark matter searches, we…
Gravitational waves from metastable cosmic strings in Pati-Salam model in light of new pulsar timing array data
Waqas Ahmed, Talal Ahmed Chowdhury, Salah Nasri +1
A series of pulsar timing arrays (PTAs) recently observed gravitational waves at the nanohertz frequencies. Motivated by this remarkable result, we present a novel class of Pati-Sa…
Probing Stochastic Gravitational Wave Background from Strings in Light of NANOGrav 15-Year Data
Waqas Ahmed, Mansoor Ur Rehman, Umer Zubair
A realistic model of , embedded in supersymmetric grand unified theory, is investigated for the emergence of a metastable cosmic string network. This…
Investigating the GmSUGRA in the MSSM through the long-lived bino NLSP at the HL-LHC
Wenxing Zhang, Waqas Ahmed, Imtiaz Khan +2
The axino, the supersymmetric partner of axion, is a well-motivated warm/hot dark matter candidate, and provides a natural solution to the relic density problem for the bino-like n…
LHC Run-3, Yukawa Unification and Dark Matter Implications in SUSY 4-2-2 model
Waqas Ahmed, Mohamed Belfkir, Salah Nasri +2
We revisit the bottom and Yukawa coupling unification in supersymmetric -- model and present for the first time the sbottom-neutralino co-annihilation scenario consist…
Hybrid Inflation, Reheating and Dark Radiation in a IIB perturbative moduli stabilization scenario
Waqas Ahmed, Athanasios Karozas, George K. Leontaris +1
We study the cosmological implications of an effective field theory model derived within a configuration of D7 brane stacks in the framework of type-IIB string theory. We consider…
