We study the Oð4Þ Wilson-Fisher fixed point in 2 + 1 dimensions in fixed large-charge sectors identified by products of two spin-j representations (jL; jR). Using effective field theory we derive a formula for the conformal dimensions D(jL; jR) of the leading operator in terms of two constants, c3=2 and c1=2, when the sum jL þ jR is much larger than the difference jL − jR . We compute D(jL ; jR) when jL = jR with Monte Carlo calculations in a discrete formulation of the Oð4Þ lattice field theory, and show excellent agreement with the predicted formula and estimate c3=2 = 1.068(4) and c1/2 = 0.083(3).
