Black contours: Enhancement of the down- (left) and strange-quark (right) 125 GeV Higgs Yukawa couplings in the up-type SFV 2HDM, as a function of the alignment parameter cos (β − α) and the Yukawa coupling of the second Higgs doublet to down quarks κ d (left) or strange quarks κ s (right). Purple: D − D ¯ mixing bounds on the … WebThe "charm" quark was so named when it was proposed because it brought a "charming" symmetry to the weak interaction, which we now understand is because it completes the second generation of quarks, along with the strange quark. When a third generation of quarks was proposed, they were called top and bottom by analogy to the up and down …

WebQUARK is a versatile ice axe designed for technical mountaineering and ice climbing. Its balance and ICE pick allow solid placements on a variety of types of ice. The TRIGREST and GRIPREST handrests make it easy to handle and comfortable in many different situations. In particle physics, a generation or family is a division of the elementary particles. Between generations, particles differ by their flavour quantum number and mass, but their electric and strong interactions are identical. There are three generations according to the Standard Model of particle physics. Each … See more Each member of a higher generation has greater mass than the corresponding particle of the previous generation, with the possible exception of the neutrinos (whose small but non-zero masses have not been accurately … See more The origin of multiple generations of fermions, and the particular count of 3, is an unsolved problem of physics. String theory provides … See more Fourth and further generations are considered unlikely by many (but not all) theoretical physicists. Some arguments against the possibility of a fourth generation are based on the subtle modifications of precision electroweak observables that … See more • Grand Unified Theory • Koide formula • Neutrino mass hierarchy See more
