2023年12月26日 · disclaimer: This post is about a proton electric dipole moment, but it might be the case that the proton electric quadrapole moment is known to be non-zero.. I don't know the physics of quarks and gluons, but I know some basic electric theory and some experimental physics. The potential from some source charge near the origin can be written as

2013年10月19日 · The grey sphere in Wikipedia's site, shows the region where quarks make the proton, in other terms, if the wave-function shows the probability of finding a particle in a region of space, then this sphere shows the probability where you can find the essential quarks making up a …

2008年9月11日 · Proton mass is 1.67262158 × 10E-27 kilograms, and its velocity is proportional to its energy. So then, in E=mc^2, you only plug the m, and you will always get the same value.

2008年2月24日 · The question is to calculate the speed of a proton that is accelerated from rest through a potential difference of 120V. Qp(charge of proton) ~ 1.60E-19C...with this, DeltaU = Qp*DeltaV...in which DeltaU is positive. It makes sense since the proton is …

2008年3月14日 · Have we successfully removed a proton from an atom, or added one? Can we take mercury and remove a proton, or add one to platinum, and so make gold? Has this been done in a lab? k

2020年4月18日 · The centerpiece is the set of eighteen baryons: particles, like the proton and neutron, composed of three lightweight quarks. This Insight provides an introduction to these baryons, whose discovery and classification constitute perhaps the first great achievement of what is now known as the standard model of particle physics.

2013年3月18日 · Hi, so we are studying quantum physics at college and I just want to understand this concept of decay. Please could someone help me?

There is zero experimental evidence for proton decay to positron. The current state of the field is that the fact that the proton and positron have the same quantum of charge allows the possibility that a proton could decay to a positron and some neutral detritus.

2012年12月26日 · The proton's mass is m = E/c 2 where E is the total energy. E includes rest mass of quarks, but also includes the kinetic energy of both quarks and gluons, plus potential energy due to the strong interaction.

2003年9月17日 · In elementary physics, it is said that the neutron can "sorta" be thought of as a proton plus an electron together. The mass of the neutron is slightly higher than a proton, by approximately the mass of an electron; in beta decay, a neutron decays into a proton, electron and neutrino; the neutron is neutral, since the two charges cancel.
