ON THE WRAPPING CORRECTION TO SINGLE MAGNON ENERGY IN TWISTED ${\mathcal N}=4$ SYM

We apply Zeilberger summation to derive a closed formula for the wrapping correction to one-impurity states in the [Formula: see text] sector of the β-deformed [Formula: see text] SYM theory at β = 1/2. As an application depending heavily on the result, we compute the large volume expansion of the wrapping correction.
