Abstract

Abstract : The potential of the e + e - → ν ν ¯ H process in the first stage of CLIC considering center-of-mass energy of 380 GeV and assuming the baseline integrated luminosity of 500 f b - 1 is examined to probe CP-conserving dimension-six operators in a model-independent Standard Model effective field theory framework. In the analysis, a detailed fast simulation on e + e - → ν ν ¯ H signal processes and dominant backgrounds is performed including parton showering with PYTHIA and detector simulation based on ILD type detector with DELPHES in MadGraph. The obtained best limits on c ¯ H B, c ¯ W = - c ¯ B, and c ¯ H W are - 4.82 ; 1.53 × 10 - 2, - 5.11 ; 4.13 × 10 - 3, and - 6.58 ; 5.55 × 10 - 3, respectively.
