Each "parent" radioactive isotope eventually decays into one or at most a few stable isotope "daughters" specific to that parent.
If there were any hints of departures from the Standard Model -- if it decayed into one type of particle more-or-less frequently than predicted -- it could be an extraordinary hint of new physics.
Suddenly, with huge mass differences between light particles and heavy ones, the heavy ones spontaneously decay into the lighter ones on very short timescales, especially when the energy (E) of the Universe drops below the mass equivalent (m) needed to create these unstable particles via E = mc2.
As bars of blue, red, green, and grey grow, decay, and blend into one another, a funny feeling takes over viewers of Carsten Nicolai's unicolor: that of being psychologically manipulated by varying wavelengths of light.
It and other Latin American capitals have decayed into what one historian has described as "post-apocalyptic". After dark, the 120-block historic center is a ghost town, with vagrants and patrolling cops the main signs of life.
Map layers depicting infrastructure, land use, and modified vegetation were each scored for site impact and distance decay, and then combined into one map surface.
For more than 25 years, a French Renaissance-style chateau on Central Park West between 105th and 106th Streets has sat vacant, falling ever further into decay as one developer after another abandoned efforts to restore it.
Each of these trees were classified into one of five decay classes, based on their visual appearance, mainly the presence or absence of needles, and branches of different order (Aakala 2010).
For example, when a Higgs boson decays into two Z bosons, one can decay into a charged lepton pair and the other into a pair of neutrinos, leaving as final state an oppositely charged lepton pair and ETmiss.
They classified each tooth into one of seven types: normal, decayed, missing, filled, treated by diammine silver fluoride, observation required, or treated by a dental sealant.
