Description
We investigate the prospects for the discovery of neutral Higgs
bosons with a pair of muons by direct searches at the CERN Large
Hadron Collider (LHC) as well as by indirect searches in the rare decay
Bs → μ+ μ- at the Fermilab Tevatron and the LHC.
Promising results are found for the minimal supersymmetric standard
model, the minimal supergravity (mSUGRA) model, and supergravity
models with non-universal Higgs masses (NUHM SUGRA).
For \tan β \simeq 50, we find that
(i) the contours for a branching
fraction of B(Bs →μ+μ-) =
1 x 10-8
in the parameter space are very close to the 5σ contours for
pp → bφ0 → b μ+μ- + X, φ0 =
h0, H0, A0
at the LHC with an integrated luminosity (L) of 30 fb-1,
(ii) the regions covered by
B(Bs → μ+μ-) ≥
5 x 10-9 and the discovery
region for bφ0 → bμ+μ-
with 300 fb-1 are
complementary in the mSUGRA parameter space,
(iii) in NUHM SUGRA models, a discovery of
B(Bs → μ+μ-)
\simeq 5 x 10-9 at the LHC will cover
regions of the parameter space beyond the direct search
for bφ0 → bμ+μ- with
L = 300 fb-1.
