Conspiracy theories, UFO sightings, ex-employee confessions, secret tunnels — there’s no shortage of Area 51 controversies. While some of the conspiracy theories are extremely far-fetched, others might make some sense.

There are six types, known as flavors, of quarks: up, down, strange, charm, bottom, and top. Up and down quarks have the lowest masses of all quarks. The heavier quarks rapidly change into up and down quarks through a process of particle decay: the transformation from a higher mass state to a lower mass state.Each family contains two quarks. The first family consists of Up and Down quarks, the quarks that join together to form protons and neutrons. • The second family consists of Strange and Charm quarks and only exist at high energies. • The third family consists of Top and Bottom quarks and only exist at very high energies.

Like the up and down quarks, which differ in electric charge and therefore in how they can combine to make integer-charge baryons and mesons, the charm/strange and top-bottom quarks work slightly differently with respect to the kinds of combinations they can form.Quark “ colours” The interpretation of quarks as actual physical entities initially posed two major problems. First, quarks had to have half-integer spin (intrinsic angular momentum) values for the model to work, but at the same time they seemed to violate the Pauli exclusion principle, which governs the behaviour of all particles (called fermions) having odd half-integer spin.Charm quarks are the second heaviest, behind top quarks. They never form in ordinary conditions on Earth; a particle accelerator is necessary to make them.

Quarks have fractional electric charge values—either − 1⁄3 or + 2⁄3 times the elementary charge, depending on flavor. Up, charm, and top quarks (collectively referred to as up-type quarks) have a charge of + 2⁄3, while down, strange, and bottom quarks ( down-type quarks) have − 1⁄3. Antiquarks have the opposite charge to their ...The Strange Quark. The strange quark comes under the third lightest among all. Strange quark is denoted by s, and its antiparticle is denoted by S. Its electric charge is -1/3 e. The Charm Quark. The meson which is called a J/Psi particle is an example of the charm quark. Charm Quark is denoted by C, and its antiparticle is denoted by C.The strange quark or s quark (from its symbol, s) is the third lightest of all quarks, a type of elementary particle. Strange quarks are found in subatomic particles called hadrons. Examples of hadrons containing strange quarks include kaons ( K ), strange D mesons ( D s ), Sigma baryons ( Σ ), and other strange particles .of quarks, but are considered to have more complicated structures than ordinary hadrons such as protons and neutrons, which were already mentioned in the early stages of the prediction of quarks and soon after the discovery of the charm quark [1,2].

There is a pattern of these quark decays: a quark of charge +2/3 ( u,c,t) is always transformed to a quark of charge -1/3 (d,s,b) and vice versa. This is because the transformation proceeds by the exchange of charged W bosons, which must change the charge by one unit. The general pattern is that the quarks will decay to the most massive quark ...The NNLO fit results with free and fixed strangeness are also indicated, and their ratios are shown below the cross section plots. - "Determination of the strange-quark density of the …

Nambu and and Han describe the SU(3) symmetry for quarks.2 Answers. The terms strange and strangeness predate the discovery of the quark, and were adopted after its discovery in order to preserve the continuity of the phrase; strangeness of anti-particles being referred to as +1, and particles as −1 as per the original definition. For all the quark flavour quantum numbers (strangeness, charm ...

The idea of a multiple universe reality is no longer considered speculative or implausible by many physicists; rather, it is deemed inescapable. Distinct concepts of the multiverse spring from quantum mechanics, cosmology, string theory-based cosmology, and ideas about a mathematics based reality that borders on the religious.In this accessible and …

The Standard Model predicted 6 types of quarks: up, down, top, bottom, charm, and strange. They are differentiated based on properties such as mass and charge. The last to be experimentally confirmed was the heaviest, the top quark. Having confirmed the existence of each type of quark, attention turned to combinations of quarks.

Feb 2, 2023 · In this mechanism, the formation of the charm hadron is through the capture of light quarks in the medium by the charm quark with the same velocity.

With this discovery, there were now two complete generations of particles: the first—the electron and the up and down quarks; the second—the short-lived muon, charm, and strange quarks. Subatomic particle - Quarks, Hadrons, Leptons: The discovery of the pion in 1947 seemed to restore order to the study of particle physics, but this order did not last long. Later in the year Clifford Butler and George Rochester, two British physicists studying cosmic rays, discovered the first examples of yet another type of new particle. The new particles were heavier than the pion or muon ...

are exactly cancelled. At higher order levels, in limit of equal masses for up and charm quarks FCNC diagrams cancel each other exactly. If masses of up and charm quark are not equal, than residual e ect of FCNC decays would be observable and its size will depend on the ratio of masses of two up type quarks.
