Wilson lines as superconformal defects in ABJM theory: a formula for the emitted radiation
Abstract We study operator insertions into 1/2 BPS Wilson loops in N $$ \mathcal{N} $$ = 6 ABJM theory and investigate their two-point correlators. In this framework, the energy emitted by a heavy moving probe can be exactly obtained from some two-point coefficients of bosonic and fermionic insertio...

| description | Abstract We study operator insertions into 1/2 BPS Wilson loops in N $$ \mathcal{N} $$ = 6 ABJM theory and investigate their two-point correlators. In this framework, the energy emitted by a heavy moving probe can be exactly obtained from some two-point coefficients of bosonic and fermionic insertions. This allows us to confirm an early proposal [1] for computing the Bremsstrahlung function in terms of certain supersymmetric circular Wilson loops, whose value might be accessible to localization techniques. In the derivation of this result we also elucidate the structure of protected multiplets in the relevant superconformal defect theory and perform an explicit two-loop calculation. |
