Meson (/ ˈ m ɛ. s ɒ n /) is a software tool for automating the building (compiling) of software. The overall goal for Meson is to promote programmer productivity. [3] Meson is free and open-source software written in Python , under the Apache License 2.0 .

The existence of neutral B meson oscillations is a fundamental prediction of the Standard Model of particle physics. It has been measured in the B 0 – B 0 system to be about 0.496 / picoseconds, and in the B 0 s – B 0 s system to be Δm s = 17.77 ± 0.10 (stat) ± 0.07 (syst) / picosecond measured by CDF experiment at Fermilab.

Mesonen (von griechisch: τὸ μέσον (tó méson) „das Mittlere“) sind instabile subatomare Teilchen.Aufgebaut aus einem Quark-Antiquark-Paar bilden sie eine der zwei Gruppen von Hadronen.Von der zweiten Hadronengruppe, den Baryonen, unterscheiden sich Mesonen durch ihren ganzzahligen Spin; sie sind somit Bosonen.. Der Name „Meson“ wurde wegen der …

A muon (/ ˈ m juː ɒ n / MYOO-on; from the Greek letter mu (μ) used to represent it) is an elementary particle similar to the electron, with an electric charge of −1 e and a spin of 1 ⁄ 2, but with a much greater mass.It is classified as a lepton.As with other leptons, the muon is not known to have any sub-structure – that is, it is not thought to be composed of any simpler particles.

Solid-state physics. In solid-state physics, an electron hole (usually referred to simply as a hole) is the absence of an electron from a full valence band.A hole is essentially a way to conceptualize the interactions of the electrons within a nearly full valence band of a crystal lattice, which is missing a small fraction of its electrons. In some ways, the behavior of a hole within a ...

Un méson est, en physique des particules, une particule composite (c’est-à-dire non élémentaire) composée d'un nombre pair de quarks et d'antiquarks.. Le terme « méson » vient du grec μέσον, meson, qui signifie « le milieu, la juste mesure ».. Caractéristiques

Gauge bosons are carrier particles for three of the four fundamental forces.In the Standard Model of particle physics, there are four kinds of gauge bosons.The three gauge bosons are as follows: W and Z bosons, which carry the weak force; Gluons, which carry the strong force; Photons, which carry the electromagnetic force; The only remaining fundamental force that has no known …

In particle physics, a kaon (/ ˈ k eɪ. ɒ n /), also called a K meson and denoted K, is any of a group of four mesons distinguished by a quantum number called strangeness.In the quark model they are understood to be bound states of a strange quark (or antiquark) and an up or down antiquark (or quark).. Kaons have proved to be a copious source of information on the nature of fundamental ...

Como muchos de esos símbolos podían referirse a más de una partícula, se añadieron reglas extra : En este esquema, las partículas con J P = 0 − se conocen como pseudoescalares, y a los mesones con J P = 1 − se les llama vectores.Para otras partículas, el número J se añade como subindice: a 0, a 1, χ c1, etc.; Para muchos de los estados ψ, Υ y χ es común incluir la ...
