Jet-substructure physics is a relatively new and exciting topic in particle physics. In collider experiments, such as the Large Hadron Collider (LHC) experiment located at CERN, a typical observed event is characterised by a handful of standard constructs such as isolated leptons/photons and QCD jets. In a traditional collider physics project, these standard tagged-objects are considered to be irreducible, and only the kinematic information of these objects is used. In a typical study on collider phenomenology, for example, one uses this information in order to distinguish and identify events due to Beyond Standard Model physics (signal events) from events due to the Standard Model physics (considered background). Substructure techniques extend traditional collider phenomenology in order to extract further information out of each collider event.

Given the investment and effort that the particle physics community of the world has made at the LHC, the need and importance of the proposed research cannot be overstated. Since the LHC has started taking data at even higher center of mass energy, which would give rise to an even higher number of objects with large transverse momentum, resulting in more collinear particles per event, the timing of these discussions could not be more appropriate.

One of the most positive features of the field of jet-substructure is that, even in a nascent stage, it was accompanied by fruitful dialogues between theorists and experimentalists from the LHC and the Tevatron at Fermilab. The goal of this program is to bring together leading experts in both theoretical and experimental techniques in the field of jet substructure physics (i) to discuss latest progress from the LHC (ii) to foster discussions/interactions between experts and newcomers in the field and (iii) to boost collaboration among participants.

A tentative list of topics for discussion is presented below:

  1. New ideas in jet substructure physics
  2. Taggers and their performances with pileup
  3. Detector performances for boosted objects
  4. Jets from heavy ion collisions
  5. Calculations in jet substructure physics

The main event (January 23-28) consists of slots for plenary talks from the experts and slots reserved for discussions/interactions as well as collaborative meetings among participants.

In the first two days of the meeting (January 21-22) we plan to organise a preparatory school consisting of specialized lectures for non-experts (geared mainly towards advanced students and postdocs). Lectures will be given by experts from the pool of participants. These lectures will be primarily designed to prepare non-experts for the upcoming main event.

Application

We seek applications from young scholars (postdocs and advanced graduate students). Priority will be given to the scholars who have already demonstrated some aspects of familiarity in the topic of jets at LHC (especially in jet-substructure). Faculty participation is by invitation only.
