Significance for science
Accurate determination of the mixing parameters in the system of D^0 mesons, and especially of the CP violating parameters, plays an important role in constraining possible values of the parameters included in models that describe the processes and particles beyond the currently verified Standard Model (SM) of interactions among particles (often referred to as New Physics). The measurements, in combination with a possible discovery of New Physics processes (NP) at the Large Hadron Collider at Cern, will help in identification of the correct models of New Physics. Within the project we have developed experimental methods and performed the most precise measurements in several charmed hadron processes.
Most of the precision measurements, motivated by the SM tests and search for processes beyond the SM, are focused on the analysis of flavor changing neutral currents (FCNC), which proceed through a higher order processes. Due to that they are more sensitive to the possible NP contributions than some of the more abundant processes in the SM. Among the flavor changing neutral current processes the mixing of D0 mesons (and CP violation) is one of the rare phenomena involving the FCNC's of the uplike quarks (c quarks, while most of the other measurements are devoted to studies of FCNC's of the downlike quarks, specifically b and s). Because of that the results of the ongoing measurements within the scope of the project are complementary to the results of precision measurements in B meson physics, and represent independent test of a large variety of NP models.
Significance for the country
While the direct influence of the basic research on the development is difficult to estimate, some the tools and methods used in research can be applied to the non-strictly scientific fields. An example is the Grid computing technology. Within the project we have developed a local computing cluster as a part of the Belle virtual organization. In the future the application will be further developed with the aim of a large scale simulated data production, and organizing the local Grid center to be exploited in the future measurements with the Belle II detector.
Probably even more important impact arises from the continuing involvement in the cutting-edge research efforts and technology used in the experiments, where the accumulated knowledge is transferred to students through the pedagogical work at universities (members of the project group take active part in teaching at both under- and post-graduate level).
Last but not least, excellency of scientific results represent a promotion of Slovenia through regular contacts among world-wide community of scientists at the international conferences, within the international Belle collaboration and through publication of papers in the international scientific journals.
