Decay mode of the product nuclei and the properties of the nuclides after decay.
After this fast decay portion, the device switches onto the slow
decay mode for the remaining fixed off-time period, which lasts 3.25 [micro]s.
Tevatron scientists found that the observed Higgs signal in the combined CDF and DZero data in the bottom-quark
decay mode has a statistical significance of 2.9 sigma.
(1983) Observation of exclusive
decay modes of b-flavored mesons.
If the signal-to-background ratio is kept at 10:1, after a single reactor cycle (roughly 30 days) not only will this
decay mode be definitively seen for the first time, but the spectrum of photons from radiative [beta]-decays will be measured at the 5 % level.
A, B, and C are zero time intercepts of the three curves that comprise three modes of positron decay, and represent the number of positrons annihilated by each
decay mode, respectively.
"By having the geochemical measurements and the direct measurements in agreement,' he says, "the theorists [who calculate the probability of this
decay mode occurring in the nucleus] have to face the fact that the half-life value we obtained is the correct one.'
The contribution of each
decay mode to [[kappa].sup.2.sub.[GAMMA]] includes the couplings and phase-space factors relevant to that decay.
But we only concentrate on the diphoton
decay mode in this paper as stated earlier.
Production cross-sections and the analysis for the [[mu].sup.*] [right arrow] [mu][gamma]
decay mode are presented in Section 3.
We take into account the signal in [v.sup.*] [right arrow] eW
decay mode of excited neutrinos as well as corresponding backgrounds at LHeC with [square root of s] = 1.3 TeV and [square root of s] = 1.98 TeV.
