Topics of interest:

• Impact of NLO effects on single vector-like quark (VLQ) production (forward tagging jet is a useful tool, how affected by NLO)?
• VLQ decays to W/Z/h+q, with q a light quark are plausible, should be explored for both single and pair production: investigate which channels remain unexplored and if that leads to a significant sensitivity loss.
• Are low mass VLQ B (decaying to h/Z+b) excluded?
• In case of observation, what can we learn about the VLQ nature (multiple, UV completion) from chirality of couplings to W,Z, BRs,…
• What about heavy (charged or neutral) tau partners? (Searches in V/h+tau) Or l^-N^++ production? Leads to similar final state as W_R production but with opposite-sign dilepton, but at much lower scale. Florian Goertz, Adrian Carmona
• What is the sensitivity to additional higgses produced in pairs and each decaying to VV, Vgamma or gammagamma? A group on general study has been set up in the Higgs WG: Pair production of heavy Higgs partners
• Vector boson pair production can be mediated by t-channel Q. What is the impact on V pT etc? Edward Boos, Jose Santiago, Aurelio Juste, Giacomo Cacciapaglia

Volunteers:

* Benjamin Fuks, Aldo Deandrea (for the NLO study)

* Daniele Barducci, Aurelio Juste, Edward Boos, Jose Santiago, Devdatta Majumder: discrimination of the chirality of the VLQ. Impact of higher masses vs SM top approach. (Perhaps starting look at X53→W+W+b) Compare bW with tZ or tH decay channels for T23.

1. Tevatron and LHC paper: http://arxiv.org/pdf/1412.0139.pdf, https://cds.cern.ch/record/1528567/files/TOP-12-025-pas.pdf, http://arxiv.org/pdf/hep-ex/0411070.pdf How well we can determine these factors?

* Giacomo Cacciapaglia: pair produced Higgs partners (transversal group in Higgs WG), VLQ → H jet (feeds to exotic Higgs production group).

* Alberto Parolini: VLQ nature, tau partners, more Higgses.
