Wilson fermion
In lattice field theory, Wilson fermions are a fermion discretization that allows to avoid the fermion doubling problem proposed by Kenneth Wilson in 1974 The inverse free fermion propagator in momentum space now reads where the last addend corresponds to the Wilson term again. wikipedia.org

Is $U(2)=SU(2) \times U(1)$? In the many textbook of standard model, i encounter the relation \begin{align} SU(2)_L \times U(1)_L = U(2)_L \end{align} Here $L$ means the left-handness, (It is a physical meaning(repres...
Not quite. There is a natural short exact sequence $$1 \to SU(2) \to U(2) \xrightarrow{\det} U(1) \to 1.$$ This sequence doesn't have a natural splitting, but it does have a splitting given by $$U(1) \ni z \mapsto \left[ \begin{array}{cc} z & 0 \\\ 0 & 1 \end{array} \right] \in U(2).$$ Such a splitt...
