Greetings.
I read somewhere that ONLY particles with an electrical charge possesses mass.
Is that true?
Thanks.

mikeu said:No, the neutron has roughly the same mass as the proton but zero charge...
fliptomato said:Mass comes from the breaking of the SU(2)xU(1) gauge symmetry by the Higgs boson. The Higgs gets a "vacuum expectation value" (vev) at low energies and creates effective mass terms in the Lagrangian. (There are no mass terms in the high-energy Lagrangian--they break chiral symmetry.)
Electric charge comes from that same SU(2)xU(1) gauge symmetry, the charge of a particle depends on its representation in the symmetry group.
In this sense, the mass terms for particles and the electric charge of those particles can be traced back to this SU(2)xU(1) symmetry, but they're two very different things.

pallidin said:OK, but out of the fundamental particle group, does ANY fundamental particle without charge have mass?
ZapperZ said:Example: Neutrinos, all three flavors.
Zz.
Hey, I think it would be better to say that every charged particle has mass.pallidin said:Greetings.

From viewing http://physicsweb.org/articles/world/11/7/3/1 it is clear that there is a growing experimental evidence that the neutrino has mass.
I would posit that such evidence lay's to rest the notion that electrical charge is immutably related to mass.
Thanks again.

If a body moves towards C, then its Mass increases thus, conversely if a body comes to rest, so does its Mass?
There are paradox's for Mass to Energy Ratio's, this is evident when has a Zero-Point-Energy source...and then accelerate's it to close to the speed of light..this translates to an Infinity-Point-Energy source?
When that article states that most of the mass of, say, a proton is comprised on the (kinetic) energy of its quarks and gluons, I think you can infer that the proton is at rest. If the proton is not at rest, then you are measuring its relativistic mass. As 'mass' is generally taken to mean 'rest mass', it's not helpful to consider the proton as anything other than at rest. It's rest mass, then, is the sum of the relativistic masses of its components (quarks and gluons). Gluons have no rest mass, but because of their motion have relativistic mass (like the photon).Spin_Network said:If Mass of a body, is a Measure of its Energy, then if Energy Changes, so does Mass!

El Hombre Invisible said:Can the Z0s be observed?
El Hombre Invisible said:Sorry, I meant directly observed. However, I seem to have misunderstood that relevant point here that Z0s, like photons, can be virtual or real, which kind of makes my question redundant.
Meir Achuz said:The Z0 has a short lifetime, ~3X10^-25 sec, but it is just as real as other unstable particles.
Electrical charge is a fundamental physical property of matter that causes it to experience a force when placed in an electric field. It is measured in units of coulombs (C) and can be either positive or negative.
Electrical charge and mass are two independent properties of matter. However, they are related through the equation e=mc^2, where e is energy, m is mass, and c is the speed of light. This equation shows that mass and energy are interconvertible, and therefore, charged particles have an associated energy due to their charge.
The main difference between electrical charge and mass is that charge is a property of matter that results in a force in an electric field, while mass is a measure of the amount of matter in an object. Additionally, charge can be positive or negative, while mass is always positive.
Electrical charge is measured in units of coulombs (C). One coulomb is defined as the amount of charge that passes through a point in a conductor in one second when there is a constant current of one ampere (A). Charge can also be measured using an instrument called an electric meter or using an electrometer in more precise measurements.
No, mass does not have an effect on electrical charge. As mentioned earlier, they are two independent properties of matter. However, the presence of mass may affect the behavior of charged particles due to the force of gravity, but the charge itself remains unchanged.
