• Investigate the signatures arising from the decay of a heavy bosons (spin 0 and spin 1) in SM quarks and VLQs, e.g. Z'→ VLQ top, ora extra light scalars, e.g. Z' → Z a
• From the polarization of the top arising from the decay is it possible to infer the representation to which the heavy boson belongs, i.e. predict the presence of other states?

Possibile bosons involve

• spin 1 color singlet
• spin 1 color octet
• spin 0 color singlet
• …

Strategies

• spin 1 color singlet
