Project Details


The description of the experiments performed in large accelerator facilities, and thus of the Standard Model physics, requires a solid knowledge of the Sorong interaction dynamics. It is a crucial step in order to tackle the big problems that high energy physics faces nowadays. These can be summarized as follows: 1) to discern the differences between the predictions of the Standard Model and experimental data (i.e to detect new physics). 2) to quantitatively understand the strong interactions, and 3) to understand the new forms of matter that appear at finite temperature/density. Although it is not possible to solve the theory of the strong interactions (QCD) quantitatively at low energies yet, there are certain situations where it is possible to obtain model independent results. Typically, this happens when one focuses on studying certain kinematical situations. Normally this produces the existence of a hierarchy of widely separated scales, which one can take advantage of by using effective theories. In this context, the motivation of this group is to impel in a resolute way the use of effective theories of QCD in strong interaction processes. This allows us to describe in the same language different physical processes. In this project we will focus our efforts on the following physical systems: 1) systems made up of two heavy quarks (also considering its study at finite temperature) or 2) those where some of their components move at ultrarelativistic speeds. 3) also, in more general terms, we will study systems at finite temperature where an example of effective theory would be transport theory. The systems made up by two heavy quarks can be described with potential non-relativistic QCD (pNRQCD) while systems with ultrarelativistic particles can be described with soft collinear effective theory (SCET). At present, there is no other group in Spain that promotes, in a determined way, these lines of research. Our emphasis is in obtaining model (...)
