radioactive decay

The continual loss of energy by radioactive substances. Disintegration of the nucleus by the emission of alpha, beta, or gamma rays eventually results in the complete loss of radioactivity. The time required for some materials to become stable may be minutes and, for others, thousands of years.

In Section 3 we study the multilepton decay modes of the RHNs at the 13 TeV LHC and future 100 TeV pp collider.
There is a high positioning overshoot at the first step, independent of the decay mode, the actual angle change is three times bigger than the expected ones (the calculated microstep value is 6.75').
We obtain expressions for some relevant decay modes of [phi], present direct LHC constraints, LHC gluon-gluon-fusion rate for [phi] production, and LHC diphoton rate from [phi] decay for various total widths of [phi].
Partial widths of three-body decay modes where an off-shell gauge boson goes to [W.sup.+][W.sup.-] pair grow very rapidly with increasing scalar mass.
Since we choose the [[mu].sup.*] [right arrow] [mu][gamma] decay mode of the excited muon (try to identify the excited muons through its decay products), no further cut is made on jets.
A study of the potential of future high energy [e.sup.+][e.sup.-] linear colliders to probe excited spin-3/2 neutrino signals in different decay modes by considering three phenomenological currents taking into account the corresponding background was done in [8].
A less important decay mode of [[pi].sup.+] ([[pi].sup.-]), with probability of occurrence just 0.000123, is its decay into a positron (electron) and an electron neutrino (electron antineutrino) as
The final result of the measurement was expressed as a frequentist confidence interval which accounted for the fact that each [[tau].sup.-] decay mode and signal bin may have a different signal to background ratio.
One can expect that the analysis of the predictions of the model of the 4th generation for the number of events of other decay modes of the 125.5 GeV Higgs boson will provide an overdetermined system of equations for these parameters, making possible the complete test of this model.
(1-1) [q.sub.1] = [q'.sub.1] = d, decay mode becomes [B.sup.0] [right arrow] [[eta].sub.c][[pi].sup.0][K.sup.*0],
In this channel, one of the top quarks decays through SM decay mode of t [right arrow] Wb [right arrow] l[v.sub.l]b (l = e, [mu]) and the other one is considered to decay through FCNC into q + g, where q is u- or c-quark.
The symbols denote the experimental data of the photoproduction cross-section of the [phi] meson produced in its neutral decay mode in the reaction [gamma]p [right arrow] p[phi]([K.sub.S][K.sub.L]).
