Development of a graphical user interface (GUI) in MATLAB to estimate radiobiological parameters to treat cancer through the fitting of survival rate models to clinical data. The uncertainties of the fitting parameters were determined with the application of Bootstrapping.

Project: Gravitational Waves The goal of the internship was to understand the importance of GW as probes of the early Universe and how their amplitude changes with the elementary-particle masses. A point with certain values for the potential parameters was chosen, and the particles’ masses were changed. Then, it was generated a plot of GW amplitude as a function of its frequency.Later, the model was simplified by removing the sterile neutrinos.Python and the CosmoTransitions package were the tools used.During the first three weeks of the internship, there were a series of lectures and workshops given by the investigators at CFTC.At the end of the internship a final presentation was made.

Project: Novel probes of the primordial QGP (CMS group)The goal of the internship was to measure the B meson’s cross-section in Pb-Pb collisions and to study how the QGP affects the hadronization of the b quark. It was used the PbPb data collected by the CMS experiment at the LHC. It was performed a detailed study of Monte Carlo validation by extracting signal from data, and in order to do it, the sideband-subtraction and sPlot methods were employed. Instead of applying selection criteria separately to each signal-vs-background discriminating variable, a Boosted Decision Tree (BDT) method was employed, combining all variables.C++ and ROOT were the tools used.During the first week of the internship, there were a series of lectures and workshops given by the investigators at LIP.At the end of the internship a final presentation was made and a research paper was produced.
