2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/203953We study finite size effects for composite operators in the SU(2) sector of the superconformal beta-deformed N=4 SYM theory. In particular we concentrate on the spectrum of one single magnon. Since in this theory one-impurity states are non BPS we compute their anomalous dimensions including wrapping contributions up to four loops and discuss higher order effects.LaTeX, mpost, feynmf, 20 pages, 4 figures, 5 tables; v2: references added, equations (4.13) and (4.17) correctedHigh Energy Physics - Theorytext
