# Learning about spin-one-half fields

@article{Cahill2005LearningAS, title={Learning about spin-one-half fields}, author={Peter Cahill and Kevin Cahill}, journal={European Journal of Physics}, year={2005}, volume={27}, pages={29 - 47} }

It is hard to understand spin-one-half fields without reading Weinberg. This paper is a pedagogical footnote to his formalism with an emphasis on the boost matrix, spinors and Majorana fields.

### Spinors of spin-one-half fields

- Physics
- 2020

This paper reviews how a two-state, spin-one-half system transforms under rotations. It then uses that knowledge to explain how momentum-zero, spin-one-half annihilation and creation operators…

### Why creation spinors are different from annihilation spinors

- Physics
- 2019

Creation and annihilation operators transform like particles. Spinors—the coefficients of creation and annihilation operators in Fourier expansions of fields—make fields transform according to…

### Spinors Made Simple

- Physics
- 2019

A spin-one-half particle of kind n and 4-momentum p = (~ p, p) with p = −m and spin s = ±1/2 in the z direction is represented by a state |~ p, s, n〉. For fixed kind and momentum, these states form a…

### Magnetic Like Particles and Elko Spinor Fields

- Physics
- 2016

This chapter scrutinizes the theory of the so-called Elko spinor fields (in Minkowski spacetime) which always appears in pairs and which from the algebraic point of view are in class five in Lounesto…

### 2 Description of Spinor Fields in the Clifford Bundle

- Mathematics
- 2014

In this paper we recall that by construction Elko spinor fields of λ and ρ types satisfy a coupled system of first order partial differential equations (csfopde) that once interacted leads to…

### Elko Spinor Fields and Massive Magnetic Like Monopoles

- Mathematics
- 2013

In this paper we recall that by construction Elko spinor fields of λ and ρ types satisfy a coupled system of first order partial differential equations (csfopde) that once interacted leads to…

### Virtual Experiments in University Education

- Education
- 2010

Active learning and inquiry are generally promoted as important modes of learning (Bransford, Brown et al., 2003). In particular, there is a huge body of literature on inquiry and the ‘nature of…

### Feynman rules for any spin. II. Massless particles

- Physics
- 1964

The Feynman rules are derived for massless particles of arbitrary spin j. The rules are the same as those presented in an earlier article for m>0, provided that we let m → 0 in propagators and wave…

### FEYNMAN RULES FOR ANY SPIN

- Physics
- 1964

The explicit Feynman rules are given for massive particles of any spin j, in both a 2j+1-component and a 2(2j+l)-component formalism. The propagators involve matrices which transform like symmetric…
