Abstract
We give a complete classification of mass dimension-5 Lorentz-noninvariant interactions composed from the standard model fields, using the effective field theory approach. We identify different classes of Lorentz-violating operators, some of which are protected against transmutation to lower dimensions even at the loop level. Within each class of operators we determine a typical experimental sensitivity to the size of Lorentz violation.
