In the last decade, charmed and bottom meson spectroscopy have seen great success in experimental sector. Experiments like LHCb, Babar etc are providing many new states which are being added to their spectroscopy. Newly predicted states like B(5970), D_2(3000),D*(3000), B(5840) and many more still need to assign their proper place in the spectroscopy. So we explored these newly observed states in detail using the heavy quark effective theory as our model. We analysed the two-body strong decays to their ground state mesons and light pseudo-scalar mesons. We also obtain the ratios among the strong decays, which can be confronted to the
experimental data for the verification of the JP states. As a byproduct, we also study the strong decays of the unobserved states of their spin and strange partners, which can be useful for future experiments in searching for these heavy-light mesons.
