Factorization at subleading power and endpoint-divergent convolutions in h → γγ decay
Abstract It is by now well known that, at subleading power in scale ratios, factorization theorems for high-energy cross sections and decay amplitudes contain endpoint-divergent convolution integrals. The presence of endpoint divergences hints at a violation of simple scale separation. At the techni...
