Decays

Some articles on decay, decays:

Radioactive Source - Decay Chains and Multiple Modes
... The daughter nuclide of a decay event may also be unstable (radioactive) ... In this case, it will also decay, producing radiation ... This can lead to a sequence of several decay events ...
Charge Conservation - Experimental Evidence
... The best experimental tests of electric charge conservation are searches for particle decays that would be allowed if electric charge is not always conserved ... No such decays have ever been seen ... (90% Confidence Level), but there are theoretical arguments that such single-photon decays will never occur even if charge is not conserved ...
CLEO (particle Detector) - Physics Program - Quarkonium
... interpreted as decaying to B mesons because of its large decay width ... muons at the Υ(4S) demonstrated the existence of weak decays and confirmed the interpretation of the Υ(4S) decaying to B mesons ... CLEO was able, however, to observe a number of Υ(1S) decays τ+τ−, J/Ψ X and γ X X with X = π+, π0, 2π+, π+K+, π+p, 2K+, 3π+, 2π+K+, and 2π+p ...
Kaon - Parity Violation
... Two different decays were found for charged strange mesons Θ+ → π+ + π0 τ+ → π+ + π+ + π− The intrinsic parity of a meson is P=−1, and parity is a multiplicative quantum number ... Since the mesons decay through weak interactions, parity is not conserved, and the two decays are actually decays of the same particle, now called the K+ ...
CLEO (particle Detector) - History - CLEO II
... During the CLEO II era, the collaboration observed the flavor changing neutral current decays B+,0→ K*+,0 γ and b → s γ ... Decays of B mesons to two charmless mesons were also discovered during CLEO II ... These decays were of interest because of the possibilility to observe CP violation in decays such as K±π0, although such a measurement would require large amounts of data ...

Famous quotes containing the word decays:

    Every word wants to be taken literally, else it decays into a lie. But one mustn’t take any word literally, else the world becomes a madhouse.
    Robert Musil (1880–1942)

    Admiration is a very short-lived passion that immediately decays upon growing familiar with its object, unless it be still fed with fresh discoveries, and kept alive by a new perpetual succession of miracles rising up to its view.
    Joseph Addison (1672–1719)

    It breedeth no small offence and scandal to see and consider upon the one part the curiosity and cost bestowed by all sorts of men upon their private houses; and on the other part the unclean and negligent order and spare keeping of the houses of prayer by permitting open decays and ruins of coverings of walls and windows, and by appointing unmeet and unseemly tables with foul cloths for the communion of the sacrament.
    Elizabeth I (1533–1603)
