Hugonweb | Higgs Boson Cross-sections and Branching Fractions

These are just for $m_H$ = 125 GeV, and taken from 1

Decay Mode Branching Fraction Uncertainty [%]
$H\to b\bar{b}$ 0.577 3.27
$H\to \tau\tau$ 0.0632 5.71
$H\to\mu\mu$ 2.19e-04 6.01
$H\to c\bar{c}$ 0.0291 12.21
$H\to s\bar{s}$ 2.46e-04 4.88
$H\to t\bar{t}$ 0 0
$H\to gg$ 0.0857 10.22
$H\to \gamma\gamma$ 2.28e-03 4.98
$H\to Z\gamma$ 1.54e-03 9.01
$H\to WW$ 0.215 4.26
$H\to ZZ$ 0.0264 4.28
Higgs Total Width
$\Gamma_H$ 4.07 MeV +/- 3.87%

My estimate of $H\to ee$ scaling $H\to \mu\mu$ by $m_e^2/m_\mu^2$:

$B(H\to ee) \approx 5.12 \times 10^{-9}$
