Organization of the Symposium

In addition to plenary sessions, the Granada Symposium will be organised around eight discussion sessions. Four discussion sessions will run in parallel for two half-days, separated by one half-day. The discussion sessions are grouped in two blocks, offset by half a day. This will allow participants to join at least two discussion sessions.

The parallel sessions will start on Monday afternoon and last through Wednesday morning. Each session will be convened by two members of the Physics Preparatory Group. The sessions are organised around topics covered by the submission tracks, (see below). By placing the mouse in the different sessions, you will see a list of some of the relevant questions that will be addressed in each session.

  • What is the best implementation for a Higgs factory? Choice and challenges for accelerator technology: linear vs. circular?
  • Path towards the highest energies: how to achieve the ultimate performance (including new acceleration techniques)?
  • How to achieve proper complementarity for the high intensity frontier vs. the high-energy frontier?
  • Energy management in the age of high-power accelerators?
  • What areas of instrumentation R&D should be supported, and how, in order to meet the needs of future experimental programs?
  • How to preserve knowledge, technical expertise and train the future generation of experts in detector / instrumentation R&D?
  • How should HEP computing evolve in order to support future scientific programs and their specific needs?
  • What R&D activities must be supported, and how, in order to enable this computing evolution?
  • How well can the Higgs boson couplings to fermions, gauge bosons and to itself be probed at current and future colliders?
  • How do precision electroweak observables inform us about the Higgs boson properties and/or BSM physics?
  • What are the theoretical developments in QCD and EWK needed to fully capitalize on the experimental data?
  • What is the best path towards measuring the Higgs potential?
  • What are the experimental and theoretical pre-requisites to reach an adequate precision of perturbative and non-perturbative QCD predictions at the highest energies?
  • What can be learned from beams-on-target experiments at current and potential future (pre-)accelerators to test strong interactions?
  • How to probe the QGP equation of state and to establish whether there is a 1st order phase transition at high baryon density?
  • What is known about the make-up of the proton (mass, radius, spin, etc.) and how to extract it?
  • What is the role of strong interactions at very low and very high (up to astrophysical) energies?
  • What is the optimal strategy for a complete set of measurements of neutrino properties, and what is the origin of neutrino masses?
  • Is the existing experimental program sufficient to confirm or exclude the existence of sterile neutrino states with masses in the eV/c2 range?
  • How can cosmic neutrinos help to pin-down neutrino properties - oscillations and mass hierarchy?
  • How can gravitational waves help to understand the Dark Sector of the Universe?
  • To what extent can we tell whether the Higgs is fundamental or composite?
  • Are there new interactions or new particles around or above the electroweak scale?
  • What cases of thermal relic WIMPs are still un-probed and can be fully covered by future collider searches?
  • To what extent can current or future accelerators probe feebly interacting sectors?
  • How do we search for Dark Matter, depending on its properties?
  • What are the main differences between light Hidden Sector DM and WIMPs? How broad is the parameter space for the QCD axion?
  • How will Direct and Indirect DM Detection experiments inform/guide accelerator searches and vice-versa?
  • How to compare results of different experiments in the most model independent way possible? (What are the most promising experimental programs, approved or proposed to cover different regions of parameter space?)
  • Why three generations and CP violation? Are the EW and the putative flavour scales related? What is the target precision for CKM fits?
  • Lepton Flavour Violation: can it be observed for charged leptons and is it connected to lepton universality?
  • Is there CP violation in flavour-blind processes, and what is the explanation of the strong CP problem?
  • What could the impact of the Dark Sector be in flavour physics and vice versa?
