In this model, the destructive interference between the two t-channel scalar mediators to some extent alleviates the otherwise very stringent constraint from the Xenon1T experiment while the Breit-Wigner enhancement of dark matter annihilation cross section not only proves useful in satisfying the relic abundance criterion but also ensures the scope for explaining the observed gamma-ray excess in the galactic centre.trueConference Paperhttps://iopscience.iop.org/article/10.1088/1742-6596/2156/1/012020/pdf1742659621 February 20220012020cpConference Proceeding0
