The online video game platform and game creation system Roblox has numerous games (officially referred to as "experiences") [1] [2] created by users of its creation tool, Roblox Studio. Due to Roblox ' s popularity, various games created on the site have grown in popularity, with some games having millions of monthly active players and 5,000 ...
Particle identification is the process of using information left by a particle passing through a particle detector to identify the type of particle. Particle identification reduces backgrounds and improves measurement resolutions, and is essential to many analyses at particle detectors.
Since then, the particle has been shown to behave, interact, and decay in many of the ways predicted for Higgs particles by the Standard Model, as well as having even parity and zero spin, two fundamental attributes of a Higgs boson. This also means it is the first elementary scalar particle discovered in nature.
Even among particle physicists, the exact definition of a particle has diverse descriptions. These professional attempts at the definition of a particle include: [7] A particle is a collapsed wave function; A particle is a quantum excitation of a field; A particle is an irreducible representation of the Poincaré group; A particle is an ...
For first-order weak decays, that is processes involving only one quark decay, these quantum numbers (e.g. charm) can only vary by 1, that is, for a decay involving a charmed quark or antiquark either as the incident particle or as a decay byproduct, ΔC = ±1 ; likewise, for a decay involving a bottom quark or antiquark ΔB′ = ±1.
