Universal transcendentality limit of BFKL eigenvalue

Mohammad Joubat, Alex Prygarin

Research output: Contribution to journalArticlepeer-review


We consider a special limit of the BFKL eigenvalue at ν→ 0 and odd values of the conformal spin n. We show that in this limit the NLO BFKL eigenvalue can be expressed in terms of a limited set of transcendental constants with rational coefficients. We show that the leading transcendentality term in this limit is universal and does not depend on a specific value of n.
