WebSep 28, 2024 · Mashhoon’s studies of the interaction of the inertia of intrinsic spin have fostered attempts to elucidate the similarities between gravitation and electromagnetism, a research area also known as gravitoelectromagnetism [ 10 ]. Mashhoon’s concerns about the use of the locality hypothesis also extend to measuring processes [ 1, 11 ]. WebIn particle physics, a boson (/ ˈ b oʊ z ɒ n / / ˈ b oʊ s ɒ n /) is a subatomic particle whose spin quantum number has an integer value (0, 1, 2, ...). Bosons form one of the two fundamental classes of subatomic particle, the other being fermions, which have odd half-integer spin (1 ⁄ 2, 3 ⁄ 2, 5 ⁄ 2, ...).Every observed subatomic particle is either a boson or …
WebThe Standard Model consists of 17 fundamental particles. Only two of these – the electron and the photon – would have been familiar to anyone 100 years ago. They are split into two groups: the fermions and the bosons. The fermions are the building blocks of matter. There are 12 fermions, split into six quarks and six leptons. WebDec 20, 2024 · The possibility to distinguish Dirac from Majorana fermion by gravitational interaction and torsion coupling is discussed. The scattering of both Dirac and Majorana particles are the same in the spherically symmetric gravitational field up to the first order perturbation of the fermion-gravity interaction. The scattering behaviors of Dirac and …
