NOUN
- a stable quark with an electric charge of +2/3 and a mass 607 times that of an electron
How To Use up quark In A Sentence
- A free neutron, for example, will decay with a half-life of about 18 minutes into a proton, electron and antielectron-neutrino, due to a down quark decaying into an up quark via the emission of a virtual W- particle. Your Favorite Conservatives on Evolution and ID - The Panda's Thumb
- Now nuclear physicists in Japan, Russia and the US have discovered a particle that contains two up quarks, two down quarks and a strange antiquark.
- Everyday matter is composed of just three types of particles: up quarks, down quarks and electrons.
- I took an option out on pi meson production, the kind that are made of a down and anti-up quark pair. METAPLANETARY
- The antineutron, although neutral like the neutron, is distinguishable from the neutron because it is composed of two anti-down quarks and one anti-up quark.
- I took an option out on pi meson production, the kind that are made of a down and anti-up quark pair. METAPLANETARY
- The antineutron contains one anti-up quark and two anti-down quarks, giving it a charge of 0, just like the regular neutron.
- These include the charm and top quarks, which are heavy copies of the up quark, and the strange and bottom quarks, which are heavy copies of the down quark.
- This is because the proton is made of two up quarks and a down quark, while the neutron comprises two downs and an up.
- I took an option out on pi meson production, the kind that are made of a down and anti-up quark pair. METAPLANETARY
