Probing the type-III seesaw model through e~+e~- → Σ~+Σ~- at ILC

摘要

We investigate the type-III seesaw fermionic charged triplet (Σ~±) production in the process e~+e~- Σ~+Σ~at International Linear Collider (ILC), with further decay of Σ to W_ν and to H_μ. The final state decay distributions of triplets are analysed in order to check the sensitivity of their mixing with SM leptons and to understand their properties. The triplet state (Σ) having mass around 200 GeV, will be produced in large numbers at ILC with centre of mass energy of 500 GeV and a moderate integrated luminosity of 50 fb ~(-1).
