Both CMS and ATLAS potentially see anomalies in their hadronic searches for diboson resonances. This has been extensively discussed in various fora over the past few months. This forum seeks to capitalize on the integration of theory and experiment at the BOOST Conference Series, to discuss details of the experimental issues, and to provide suggestions for the LHC Run 2 theory, phenomenology, and experimental communities.

BOOST 2015 discussion panel on diboson resonances at the LHC in Run 1 and Run 2

Panelists

1. Reina Camacho
2. Bogdan Dobrescu
3. Steve Ellis
4. Tongyan Lin
5. Nhan Tran

Goals

1. Enhance and facilitate communication between the experiments and the theory community about what was actually done in these searches.
2. Generate and communicate ideas as to what the experiments should do in Run 2, in particular in the case of a “re-observation” of the anomaly.
3. Discuss concrete plausible possibilities as to what the excess could be.

Topics

• Differences in the CMS vs. ATLAS methodologies and results
• Plausibility of the anomaly as detector effect vs. statistical fluctuation vs. new physics
• New theories that might explain this (and other) anomalies
• Extensions to the Run 2 analyses to the possible sources of new physics
• New analyses not yet being performed that might corroborate an excess

Format

• Discussion topics will be coordinated among the panel members and the moderator in advance, and the panel members will be allowed to prepare a maximum of 2 slides to be uploaded to the agenda as supporting material for the discussion.
  • If panelists do wish to contribute material in the form of slides, they must be provided to the moderator by NOON at the latest.
  • The moderator will then be asked to collate these slides and associate them to the appropriate topics in order to efficiently move through any material provided.
• At the beginning of the session, the moderator will introduce the panelists and state the general topics on which the panel is asked to focus and the order in which we plan to move through those topics
• The panelists will then be encouraged to comment on these topics, and point to their supporting material only if necessary.
• Between each topic (to the extent that they can be separated) the discussion will then be opened up to the audience.

16:45 → 18:00 Panel Discussions: Future Colliders and Superboosted Objects

An extremely exciting set of efforts is underway to evaluate the physics potential and prospective designs of new very high energy machines aimed at physics goals that vary from extremely precise determination of Higgs properties and couplings to the production of multi-TeV new particles; goals that are currently out of reach of existing facilities. Nearly all of the current proposals necessitate the study of superboosted objects (W/Z/h/top) to achieve the stated physics goals. This panel discussion seeks to capitalize on the integration of theory and experiment at the BOOST Conference Series, to engage experts in these fields regarding detector options for the superboosted regime, and to propose studies at current colliders that might inform and enhance the choices to be made at a future machine.
