Issues addressed and main goals of research:
Absolutely new and unique data will be obtained in multifaceted and comprehensive research of proton-proton scattering processes. The analysis of these data will allow solving several fundamental physical problems. JINR scientists will participate in this analysis within this project.
It is expected to obtain new results and make publications on all above-mentioned tasks where JINR scientists have responsibilities. The most important tasks are the studies of the proton structure and hadron state spectrum, probing of the Standard Model at the LHC energies, search for and investigation of supersymmetry, search for the evidence of existence of new particles and new interactions. In addition, JINR intends to obtain new results that will help specify properties of already known elementary particles such as W- and Z-bosons, top quarks, heavy baryons, etc.
The implementation of this Project aimed at solving highly significant scientific problems will also bring unique applied results which may significantly change the quality of life. Among these results the experience in operation of remote monitoring systems for technically complicated devices, big data processing, development and practical use of distributed comtputing systems (GRID), and database monitoring applications in long-term large-scale experiments can be noted.

Expected results in the current year:

  1. Investigation of applicability of the Standard Model and verification of SM predictions (including interactions of heavy ions), determination of the structure of the proton at ultra-high energies (PDFs), tuning and improvement of relevant computer codes and event generators, etc.

  2. Search for the chiral Z */W * bosons in two-jet decays and in a process with more complex topology of their associative production including heavy b and t quarks.

  3. Search for (supersymmetric) charged Higgs bosons via their specific decay modes (3-lepton, etc.).

  4. Analyses of associated productions of the SM Higgs with the top-antitop pair and search for production with a single top.

  5. Search for a valence-like nonperturbative component of heavy quarks in the proton (intrinsic heavy quarks) via specific final state topology in the pp interactions.

  6. Search for new hadrons and baryons containing heavy c and b quarks and study of their properties.

  7. Measurement of the Drell-Yan triple-differential cross section and effective leptonic weak mixing angle in the Z-boson decay.

  8. New comprehensive study of the gluon structure of the proton, etc.

  9. Search for quantum black holes in the lepton+jet channel at 13 TeV.

  10. Participation in development of event trigger indexing infrastructure.

  11. Development and maintenance of the TDAQ system.

  12. Development of database monitoring applications.
