Whats the smallest mass particle? is it the electron? or the electron neutrino?
Or is there something smaller?

Any references that i may look up to further some research
The photon (and the gluon) (Nereid ducks the barrage of rotten fruit thrown by particle physics PF members).Whats the smallest mass particle?

Bah, the photon and the gluon are forces, no particles.Nereid said:The photon (and the gluon) (Nereid ducks the barrage of rotten fruit thrown by particle physics PF members).

Well, yes that must be true, otherwise the Higgs mechanism does not work. But my question really is : why is the Higgs field colourless ?Miserable said:It's because the Higgs is colourless. It doesn't interact with the gluons at tree level, so they don't develope a mass term when it acquires its VeV.

If you find a way to detect the relict neutrinos, a Nobel will surely be yours too! :tongue2:
"The force between quarks is carried by gluons (from the word ‘glue’), which, like photons, lack mass. Gluons, however, in contrast to photons, also have the property of colour charge, consisting of a colour and an anticolour. This property is what makes the colour force so complex and different from the electromagnetic force."

Question for specialist: are gluons really massless? Following http://hyperphysics.phy-astr.gsu.edu/hbase/particles/expar.html, this is not true. Also, from my (poor) understanding, it is not simply that gluons "bind" the quarks together; they are themselves, sort of, composed of a quarks pair. -- looxix 10:16 Apr 14, 2003 (UTC)
Yes they are massless, and nowhere in the linked page states they aren't. You may be confusing them with the W and Z bosons. Gluons are not composed of a pair of quarks, however they have two color charges, for instance a red-antigreen gluon.
The fact that gluons themselves have color charge causes somewhat erratic behavior(as gluons are creating and annihilating other gluons as well), including the limited range. The W and Z bosons also have limited range, but in their case it is caused by their mass.

My copy of the 2002 Review of Particle Physics states that a mass of up to a few MeV may not be precluded, so I added that to the article. -- Schnee 23:59, 26 Jul 2004 (UTC)
An electron neutrino is a type of elementary particle that has an extremely small mass and no electric charge. It is one of the three types of neutrinos, along with muon and tau neutrinos.
The mass of an electron neutrino is so small that it is difficult to measure. Current estimates place its mass at less than 1 eV (electron volt), which is about 500,000 times lighter than an electron.
Electron neutrinos are one of the fundamental particles in the Standard Model, which is the most widely accepted theory for explaining the behavior of particles and forces in the universe. They are considered to be building blocks of matter and are involved in several fundamental interactions, such as weak nuclear force.
Electron neutrinos are difficult to detect because they interact very weakly with matter. Scientists use specialized detectors, such as giant underground tanks filled with fluid, to capture the few interactions that occur between electron neutrinos and other particles.
Studying electron neutrinos can provide valuable insights into the properties and behavior of other particles in the universe. They are also important in understanding the structure and evolution of stars, as well as the formation of the universe. Additionally, research on neutrinos can potentially lead to advancements in technologies such as nuclear reactors and medical imaging.
