361 c(-p₁) + s (-p₂) → W⁺(→ ν(p₃) + e⁺(p₄)), mc=0 in NLO

361.1 cs → W⁺, processes 361–363

These processes represent the production of a W⁺ from a charm and anti-strange quark at LO. The W⁺ boson decays into a neutrino and a positron.

The NLO corrections to this LO process include a contribution of the form, gs → W⁺c. For process 361 this contribution is calculated in the approximation m_c = 0 at NLO. In order to perform the NLO calculation for a non-zero value of m_c, one must instead sum the results of processes 362 and 363 for part=tota.
