One interesting thing about this particle is that it would only be about 30 times
heavier than an electron, which is extraordinarily light by today's physics standards.
«A muon is a cousin of the electron, a couple of hundred times
heavier than the electron — they penetrate hundreds of meters of rock,» Melott said.
Specifically, Nambu's work describes how these fundamental forces can be so different, and how elementary particles, including the particles that mediate those forces, can have such disparate masses — according to the Nobel committee, the top quark is more than 300,000 times
heavier than the electron, whereas the photon has no mass at all.
Why are protons 2,000 times
heavier than electrons, yet their charges are simply equal and opposite?
Muons are about 200 times
heavier than electrons, making them more sensitive to the proton's size.
Not exact matches
Electrons whiz around the
heavier lead nucleus at 60 per cent the speed of light, much faster
than in lighter tin.
Chemists have long believed that elements
heavier than neon could share only one pair of
electrons.
Although the exact masses remain unknown, researchers estimate neutrinos to be two million times lighter
than the next
heavier particle, the
electron, and this large mass difference is one of the great puzzles of neutrino physics.
By using
electron and positron beams instead of
heavier protons, the ILC will allow physicists to probe particle properties with much greater precision
than they can at the LHC.
This causes them to become
heavier than normal, and the rules that typically apply to
electron behavior start to break down.
Because the ease with which one neutrino oscillates into another is related to the difference in those particles» masses, a suitably
heavy sterile neutrino could explain the greater
than expected number of
electron antineutrinos.
At electrical breakdown, the energies in the surging
electrons were thousands of times greater
than 10 — 19 MeV, so during the flood, bremsstrahlung radiation released a sea of neutrons throughout the crust.83 Subterranean water absorbed many of these neutrons, converting normal hydrogen (1H) into
heavy hydrogen (2H, called deuterium) and normal oxygen (16O) into 18O.
In the
electron storage ring at the ESRF, the
electrons are roughly 10000 times
heavier than at rest.
