Strange quark is denoted by S, and its antiparticle is denoted by S. Its electric charge is -1/3 e. The Charm Quark The value 4.18 + 0.04 − 0.03 (GeV) for the ¯ MS mass corresponds to 4.78 ± 0.06 GeV for the pole mass, using the two-loop conversion formula. A discussion of masses in different schemes can be found in the ``Note on Quark Masses.''. VALUE (GeV) DOCUMENT ID. TECN.

These masses typically have very different values. Quark matter's connection with the Higgs by Brookhaven National Laboratory The three valence quarks that make up each proton account for about one percent of its mass; the rest comes from The mass of down quark ranges from 4.1 – 5.7 MeV / c 2.

Therefore the mass of a medium Up quark is 224.5973 electron masses. In the pion, an up and an anti-down quark yield a particle of only 139.6 MeV of mass energy, while in the rho vector mesonthe same combination of quarks has a mass of 770 MeV! The masses of C and S are from Serway, and the T and B masses are from descriptions of the experiments in which they were discovered. Down quark is denoted by d, and its antiparticle is denoted by d. The mass of down quark ranges from 4.1 – 5.7 MeV / c 2. Its electric charge is -1/3 e. The Strange Quark. The strange quark comes under the third lightest among all.

For the moment, let's say that the central charge of both quarks is +2/3. The outer-shell electron (in its wave-form) of the d quark has a double effect: it decreases the charge from +2/3 to -1/3, while increasing the volume, i.e. mass (see Part 1 www.mass-gravity.com).

Issues in determining the mass of the top quark - CERN Document
From Physical Review D by APS the up quark has a mass of 1.5 to 4.5 MeV and the down quark has a mass of 5 to 8.5 MeV (in the mass-independent subtraction scheme as opposed to the higher values assigned in potential models, which is just gobbledygook for, there are more than one way to measure it and this is one way with a certain result) Compare that to an electron's mass of close to 0.511 quark mass ms and of the average of the up and down quark masses mud = (mu +md)/2 are obtained from lattice simulations. As explained in section C above, the simulations are generally performed with degenerate up and down quarks (mu = md) and so it is the average which is obtained directly from the computations. Below we discuss attempts to The answer, physicists believe, lies in how the quarks interact via the exchange of gluons, massless particles that hold the quarks together via nature's strongest force, and interactions among the The team finds that an up quark weighs 2.01 +/- 0.14 megaelectron-volts, whereas a down quark weighs 4.79 +/- 0.16 MeV. That’s 0.214% and 0.510% of the mass of the proton, respectively. Knowing the Because of its enormous mass, the top quark is extremely short-lived with a predicted lifetime of only 5 × 10 −25 s. As a result, top quarks do not have time before they decay to form hadrons as other quarks do, which provides physicists with the unique opportunity to study the behavior of a "bare" quark. 2012-09-17 · A very precise and unambiguous determination of the top quark mass and, hence, the possibility to derive a reliable upper bound on the Higgs mass for which the electroweak vacuum would be stable, can only be performed at an e + e − collider ILC with an energy above s = 350 GeV. Each of these particles, or “nucleons,” is composed of a dense, frothing mess of other particles: quarks, which have mass, and gluons, which do not.
