| + | **Motivations and goal** | ||
| + | |||
| + | * Exotic decays such as ρ→Tˉt can eat branching ratio from standard search channels (dilepton, dibosons), rendering these direct searches less sensitive (see e.g. [[https://arxiv.org/pdf/1511.01101.pdf]] Fig. 3) | ||
| + | * 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, or extra light scalars, e.g. Z' -> Z a | ||
| - | * 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? | ||

| + | **Strategies** | ||
| - | References: | + | * Categorize the possible decays of the identified resonances. This was done for VLQ in Les Houches 2015 |
| - | * "Search for a heavy resonance decaying to a top quark and a vector-like top quark at 13 TeV" [[https://arxiv.org/pdf/1703.06352.pdf| (arXiv)]] | + | |

| + | * Check the sensitivity of SM searches. For example the ρ→Tˉt→Ztˉt has the same final state of the SM tˉtZ search | ||
| + | * Check the sensitivity of single production mode. Also in this case the final state can be the same. However single production searches usually exploit a forward jet, which is not present here | ||
