Axion Perturbations: A General Analytical Treatment
Itamar J. Allali, Priyesh Chakraborty, JiJi Fan +1
Cosmological data provides us two key constraints on dark matter (DM): it must have a particular abundance, and it must have an adiabatic spectrum of density perturbations in the e…
The Juno Mission as a Probe of Long-Range New Physics
Praniti Singh, Shi Yan, Itamar J. Allali +2
Orbits of celestial objects, especially the geocentric and heliocentric ones, have been well explored to constrain new long-range forces beyond the Standard Model (SM), often refer…
Reduced Axion Abundance from an Extended Symmetry
Itamar J. Allali, Mark P. Hertzberg, Yi Lyu
In recent work we showed that the relic dark matter abundance of QCD axions can be altered when the Peccei-Quinn (PQ) field is coupled to very light scalar/s, rendering the effecti…
Altered Axion Abundance from a Dynamical Peccei-Quinn Scale
Itamar J. Allali, Mark P. Hertzberg, Yi Lyu
We build a model in which the relic abundance of axions is altered from the standard misalignment mechanism, either increased or decreased, due to the presence of a new light scala…
