Example text

6 Prove Eq. 60). 48). The generalization of Eq. 61) Consider now three left-chiral spinors χ , α, and β. 62) We see that the net effect of these identities is to swap the spinors appearing in the dot products. Such identities are generically referred to as Fierz identities. These particular examples of Fierz identities will prove to be very useful later in this book. 7 Prove Eq. 62). Hint: You may simply expand out completely both sides in terms of the components of the spinors and then move some of them around, or you may use Eqs.

With some practice, it is not difficult to get used to this double role of the dagger, especially when expressions are fairly short, but it is distracting to have to worry about making sense of an ambiguous notation when learning a new subject. For this reason, we will use the following convention in this book: When a dagger will be applied to a spinor field, it will represent the hermitian conjugation of each component of the spinor field in the quantum field operator sense as well as a transpose.

In this book we will be working almost exclusively with Weyl spinors, which will always be denoted by lowercase Greek letters. The few four-component spinors we will need will always be denoted by an uppercase . So whenever a bar appears above a Weyl spinor, you will know that it is in the sense of indicating dotted indices, as in Eq. 5). So far we have only introduced three types of indexed quantities: left-chiral spinors components with lower undotted indices χa and right-chiral spinors with upper dotted and upper undotted indices η¯ a˙ and ηa .
