Search For Exotic Hadrons Research Articles

Experimental overview of the experiment

The physics program of the (anti-Proton ANhiliation ar DArmstadt) experiment will address various questions related to the strong interactions by employing a multi-purpose detector system at the High Energy Storage Ring (HESR) for anti-protons of the upcoming Facility for Anti-proton and Ion Research (FAIR). The excellent antiproton beam resolution of Δp/p ~ 10−5 and the high luminosity ℒ =2×1032cm−2 s−1 will allow the precise measurement of the charmonium and open charm spectroscopy, the search for exotic hadrons like multiquarks, glueballs and hybrids, the study of in-medium modifications of hadrons and the nucleon structure.

CMD-3 detector offline software development

CMD-3 is the general purpose cryogenic magnetic detector for VEPP-2000 electron-positron collider, which is being commissioned at Budker Institute of Nuclear Physics (BINP, Novosibirsk, Russia). The main aspects of physical program of the experiment are precision measurements of hadronic cross sections, study of known and search for new vector mesons, study of the nn̄and pp̄production cross sections in the vicinity of the threshold and search for exotic hadrons in the region of center of mass energy below 2 GeV. This contribution gives a general design overview and a status of implementation of CMD-3 offline software for reconstruction, simulation, visualization and storage management. Software design standards for this project are object oriented programming techniques, C++ as a main language, Geant4 as an only simulation tool, Geant4 based detector geometry description, CLHEP library based primary generators, ROOT toolbox as a persistency manager and Scientific Linux as a main platform. The dedicated software development framework (Cmd3Fwk) was implemented in order to be the basic software integration solution and a high level persistency manager. The key features of the framework are modularity, dynamic data processing chain handling according to the XML configuration of reconstruction modules and on-demand data provisioning mechanisms.

Fundamental Physics at Hadron Experimental Hall

In the hadron hall, there are proposals to explore a broad range of physics, as follows: 1. Studies of hadron properties in the nuclear medium and searches for exotic hadrons. 2. Kaon decay experiments to study CP and T violations. 3. Muon precision physics. In this article, I describe the experimental program at hadron hall. A plan view of the hadron hall is displayed in Figure 2. It should be noted that a more detailed plan is being discussed to accomodate newly approved experiments.

A Personal Journey Through Hadronic Exotica

The search for exotic hadrons has been forever fascinating and challenging. A review of many such searches, successful and unsuccessful, in which the author has been involved, is presented.
