The Λ c → Λ ℓ + ν ℓ weak decay including new physics

Abstract We investigate the Λ c → Λℓ + ν ℓ decay with a focus on potential new physics (NP) effects in the ℓ = μ channel. We employ an effective Hamiltonian within the framework of the Standard Model Effective Field Theory (SMEFT) to consider generalized dimension-6 semileptonic c → s operators of s...
