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...
