Hint of dark matter-dark energy interaction in DESI DR2 and current cosmological dataset?
Amlan Chakraborty, Tulip Ray, Subinoy Das +2
We present new constraints on an interacting dark matter-dark energy scenario motivated by string compactification, where a scalar field adiabatically tracks the minimum of an effe…
