One of the main channels which allows for a large rate of neutralino dark matter annihilation in the early Universe is via the Higgs pseudoscalar $A$-resonance. In this case, the measured dark matter abundance can be obtained in the minimal supergravity (mSUGRA) model when $\tan\beta\sim 50$ and $2m_{\chi_1}\sim m_A$. We investigate the reaction $pp\to b\phi\to b\mu^+\mu^- +X$ (where...
