Down quark definition
WebThe down quark or d quark is the second-lightest of all quarks, a type of elementary particle, and a major constituent of matter. Together with the up quark, it forms the … WebAgain, the neutron is not an elementary particle but a composite of an up quark and two down quarks (udd). It is in fact one of the down quarks that interacts in beta decay, turning into an up quark to form a proton (uud). At the most fundamental level, then, the weak force changes the flavour of a single quark: d → u + W −

WebEach quark has \(\frac{1}{2}\) spin and gluons also have spin. The spin of these quarks and gluons contribute to proton’s spin. Their contribution to proton’s spin is only 30%. Weak Interaction: As discussed in the above, only two quark flavours, up and down, are stable and other 4 quark flavours, top, bottom, charm and strange, are unstable.
