Abstract

The space-time structure of the Higgs boson decay are carefully studied with the HBT correlation method using e $^+$ e $^-$ collision events produced through Monte Carlo generator PYTHIA 8.2 at $\sqrt{s}$ =250GeV. The Higgs boson jets (Higgs-jets) are identified by H-tag tracing. The measurement of the Higgs boson radius and decay lifetime are derived from HBT correlation of its decay final state pions inside Higgs-jets in the e $^+$ e $^-$ collisions events with an upper bound of $R_H \le 1.03\pm 0.05$ fm and $\tau_H \le (1.29\pm0.15)\times 10^{-7}$ fs. This result is consistent with CMS data.
