Don't worry about them. Now the key point: Several quarks can be combined using gluons. Any combination of a multiple of quarks is known as a hadron.

Bacteria may seem like a strange ally in the battle against cancer. But in a new study, genetically engineered bacteria were part of a tag-team therapy to shrink tumors. In mice with blood, breast, or colon cancer, the bacteria acted as homing beacons for their partners—modified T cells—as the two sought out and destroyed tumor cells.

weak decays, mediated by a W -boson, into a strange or down quark. An exception to this are decays of ground state charmonium mesons, which decay via annihilation of the charm and anti-charm quarks. Thus, open charm particles are the only ones allowing the study of weak decays of an up-type quark in a bound state.

Quarks are the most basic building block of the universe. They are subatomic particles that make up every proton and neutron in existence. There are six different varieties of quarks, which are Up, Down, Top, Bottom, Strange, and Charm. Since the earliest days of humanity, we have been obsessed with figuring out how things work.Jul 27, 2017 · Quarks are not boring at all; in fact they are of a major importance in the Standard Model. There are 6 types of quarks (plus their anti-quarks): up,down,charm,strange, top and bottom. Each one has different properties, such as electric charge, mass, color charge and spin. Strange quarks (charge − 1/3e) occur as components of K mesons and various other extremely short-lived subatomic particles that were first observed in cosmic rays but that play no part in ordinary matter. …of quarks, charm ( c) and strange ( s ), with charges of + 2/3e and − 1/3e, respectively.

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. Quarks come in three colors: red, green, and blue. (These are just labels—quarks are not actually colored.) Each type of quark (u, d, c, s, b, t) (u, d, c, s, b, t) can possess any other colors. For example, three strange quarks exist: a red strange quark, a green strange quark, and a blue strange quark. Antiquarks have anticolor.Many people want to be geniuses, but do you really know what that means? How do you know if you’re a genius?
