#Lepton spin full
It would be better to call it the Thomas formula since it appears explicitly and in full generality in the paper of Thomas. A lepton is an elementary, half-integer spin (spin ) particle that does not undergo strong interactions, but is subject to the Pauli exclusion principle. The tau lepton and its antiparticle carry the same electric charges as the electron and positron.

Also, like the electron and muon, the tau has a spin of 1/2. 2, 435 (1959))of an equivalent result obtained by those authors using the first method above. Like the electron and muon, the tau lepton appears to be pointlike no structure has been detected, and if there is any, it would have to be on a scale of less than 10 18 meters. The lightest neutral component of the VLL in this model provides a viable dark matter (DM) candidate satisfying the current relic density data as well. The formula is sometimes called the Bargmann-Michel-Telegdi formula, since the publication (Phys. In this work, we explore the signals of an S3 -symmetric two Higgs doublet model with two generations of vector-like leptons (VLLs) at the proposed International Linear Collider (ILC). The principal result is an expression for the gyromagnetic difference frequency correct up to second order in the perturbing field.

The second method is to use the Foldy-Wouthuysen transformation of the Dirac equation. Averaging methods are used to discuss the spin and orbital motion of charged leptons confined in a trap formed by perturbing a strong uniform magnetic field with a weak nonuniform magnetic or electric field. The first is to treat the spin as a classical dynamical variable, and then to write down the most general equation of motion consistent with relativistic invariance. There are two general ways to obtain this formula. 10, 998 (1969).įor a description of the experiments see the accompanying talk by A.
