DOCUMENT | EDITORS | AUTHORS | CONTENT |
Main (30-50 pages) | PBC Coordinators | PBC WGs | Highlights of the physics case of the proposed PBC experiments at CERN, and how they can address it:
physics orientations in the worldwide landscape, uniqueness of CERN context, compatibility of projects, technical feasibility, timelines and financial implications. The content of this document will be supported by the detailed information provided in the ancillary documents listed hereafter |
BSM context | BSM WG conveners | BSM WG + possible external as appropriate | Worldwide BSM physics landscape with a focus on how the proposed PBC projects fit in term of theoretical motivation and experimental sensitivity:
overview of experimental physics processes (direct production modes, decay signatures, indirect searches…) reach in term of new particle types, masses and couplings; comparison and complementarity of their sensitivities via common simplified BSM models (e.g. accelerator WIMP searches vs recoil experiments via effective operator and simple mediator test models, helioscope and LSW searches vs EDM limits via axion-like particle models, p/d vs n EDM,…); indication of mass and coupling ranges favored by current observations (DM amount, experimental&astrophysical hints, …); general suggestions for possible extension of the PBC projects discovery reach |
QCD context | QCD WG conveners | QCD WG + possible external as appropriate | Worldwide QCD physics landscape with a focus on how the proposed PBC projects fit in term of theoretical motivation and experimental sensitivity:
QCD fundamental open questions and measurements of interest for other domains. |
Experiment contributions | Proponents | Proponents | Experiments contribute to the BSM and QCD context documents by providing their sensitivity curves within the commonly agreed models and assumptions for comparison with past, present and future experiment.s |
Documents are also expected from the Collaborations with a level of details matched to the maturity of their project:
physics motivation; expected sensitivity; detector layout; estimated timeline and cost; Collaboration structure.
N.B. these documents stay under responsibility of the Collaborations and can be the basis for possible future consideration of the projects by the SPSC and LHCC |
Complex Performance | Complex Study Group | Complex Study Group | Injector complex performance after LIU:
proton delivery through the CERN accelerator complex in view of the potential provided by LIU, intensity limitations and possible mitigation, considerations on the optimization of the delivery rates. |
BDF Comprehensive Design Study | BDF WG | BDF WG | Conceptual Design of the Beam Dump Facility:
Complete technical feasibility studies, layout and performance from SPS extraction to experiment hall, sitting and civil engineering, interconnection to the SHiP detector and to possible additional detectors, possible longer term use as a general high intensity facility, construction schedule and costing. |
EDM | EDM WG | Collab. EDM | Fully developed feasibility study of the proton/deuteron EDM storage ring:
ring layout options; experimental aspects of the EDM measurement (e.g. systematics); initial civil engineering studies for a possible siting at CERN; timeline and cost estimate, collaboration structure |
Conventional Beams Upgrades | CB WG | CB WG | Description of the conventional beam upgrades associated to the proposed projects:
technical feasibility; schedule and cost; identification of potential areas of conflict between projects siting in available experimental halls. Level of details to be matched to the available manpower for the studies, with a priority to implementations possible after LS2:
NA62++ beam dump, NA64++ and MUE muon beams, NA61++ higher intensity ion beam. Reliable estimates of the orders of magnitude of the costs of the COMPASS RF-separated beam and of the KLEVER K0 beam are also needed. |
LHC Fixed Target | LHC-FT WG | LHC-FT WG | Study of the implementation of LHC internal fixed targets in the LHCb and ALICE areas:
technical description of the discussed options (gas targets with and without polarisation, crystals, etc…); estimation of the maximal luminosities achievable for each option, compatible with the experiments and LHC constraints. |
Technology Support | Technology WG | Technology WG | Exploration and evaluation of possible technological contributions of CERN to non-accelerator projects possibly hosted elsewhere:
survey of suitable experimental initiatives and their connection to and potential benefit to and from CERN; description of identified initiatives and how their relation to the unique CERN expertise is facilitated. |
AWAKE | AWAKE Study Group | AWAKE Study Group | Exploratory study of possible applications of the AWAKE concept:
development of physics cases and experimental design; accelerator systems and realistic range of parameters; possible infrastructure and siting. |
nuSTORM | nuSTORM Study Group | nuSTORM Study Group | Updated broad outline of a possible nuSTORM implementation at CERN. |
Gamma Factory | Gamma Factory Study Group | Gamma Factory Study Group | Exploratory study of the concept feasibility:
results of initial tests and extrapolated performance; elaboration on the corresponding physics reach. |
