• We simulate the Z’ decay process(Z’ -> ZH -> bbμ+μ-)
under the conditions of different coupling
strength gv.
Z’=1TeV
Z’=2TeV
Z’=3TeV
Weekly report
• The variation of the bbത invariant mass (reconstructed by a single fat jet comes from the Z’) efficiency
with different coupling strength every 10000-events simulation.
