Putting the Brakes on Axion Strings: Friction and Its Impact on the QCD Axion Abundance
Anson Hook, Rajrupa Mondal, Shourya Mukherjee
A compelling production mechanism for QCD axion dark matter is from the scaling dynamics of early universe axion strings. We show that in DFSZ-like models containing tree-level int…
Majorana Neutrinos, Exceptional Jordan Algebra, and Mass Ratios for Charged Fermions
Vivan Bhatt, Rajrupa Mondal, Vatsalya Vaibhav +1
We provide theoretical evidence that the neutrino is a Majorana fermion. This evidence comes from assuming that the standard model and beyond-standard-model physics can be describe…
Non static Global monopole in Lyra geometry
F. Rahaman, R. Mondal
A class of non static solutions around a global monopole resulting from the breaking of a global S0(3) symmetry based on Lyra geometry are obtained. The solutions are obtained usin…
Vacuumless cosmic strings in Einstein Cartan theory
F. Rahaman, B. C. Bhui, A Ghosh +1
The gravitational fields of vacuumless global and gauge strings have been investigated in the context of Einstein Cartan theory under the weak field assumption of the field equatio…
Global monopole, dark matter and scalar tensor theory
F. Rahaman, M. Kalam, R. Mondal +1
In this article, we discuss the space-time of a global monopole field as a candidate for galactic dark matter in the context of scalar tensor theory.
Thin Domain Walls in Lyra Geometry
F. Rahaman, M. Kalam, R. Mondal
This paper studies thin domain walls within the frame work of Lyra Geometry. We have considered two models. First one is the thin domain wall with negligible pressures perpendicula…
