WebAug 26, 2024 · Internal quark mass effects from the bottom and charm quark are expected to become important in higher orders. The minimal term of the series is attained when the typical loop momentum is of order \(\varLambda _\mathrm{QCD}\). At this scale the theory is a theory of three massless flavours, independent of whether the heavy quark was the top ...

WebSince the D mesons are the lightest mesons containing a single charm quark (or antiquark), they must change the charm (anti)quark into an (anti)quark of another type to decay. Such transitions involve a change of the internal charm quantum number, and can take place only via the weak interaction.
The charm quark, charmed quark or c quark (from its symbol, c) is the third-most massive of all quarks, a type of elementary particle. Charm quarks are found in hadrons, which are subatomic particles made of quarks. Examples of hadrons containing charm quarks include the J/ψ meson ( J/ψ ), D mesons … See more Some of the hadrons containing charm quarks include: • D mesons contain a charm quark (or its antiparticle) and an up or down quark. • D s mesons contain a charm quark and a strange quark See more • Quark model See more • R.
