Students
Panagiotis Assiouras is a Phd student at the National Technical University of Athens and he works at the Detector Instrumentation laboratory of the CMS group of the Institute of Nuclear & Particle Physics at the N.C.S.R. “Demokritos”. He is participating to the Phase-II Upgrade of the CMS Tracker. His research interests are experimental particle physics, detector physics and instrumentation for nuclear and particle physics. Ηe has worked on TCAD simulations and electrical characterization measurements of silicon sensors and test structures for the new silicon detectors that will be installed on the phase-II upgrade of the CMS experiment. Also he has worked on the preparation and the upgrade of the laboratory to a Process Quality Control (PQC) center for the Outer Tracker sensors. Currently he is at the final stage of writing he’s phd thesis. He has graduated from the school of Applied Mathematical and Physical Sciences at the National Technical University of Athens. As an intern he worked at Detector Instrumentation Laboratory (DIL) of Institute of Nuclear & Particle Physics at N.C.S.R. “Demokritos” where he focused on the study of silicon detectors and after that he held his diploma thesis at NSCR Demokritos in which he worked on capacitance simulations on silicon micro-strip and micro-pixel detectors, by using an numerical algorithm, for solving the Laplace equation. He has also obtained a masters degree in Physics and Technological Applications at National Technical University of Athens. In his master thesis he worked at N.C.S.R. “Demokritos” on the electrical characterization of silicon detector prototypes for high energy physics experiments for the upcoming phase 2 upgrade of the CMS experiment at LHC. During his MSc studies, he has also worked as an intern at the Institute of High Energy Physics at Vienna. He has been a laboratory assistant at NTUA for the detector instrumentation course. His complete list of publications can be found on INSPIRE-HEP.
Vassilis Tsourapis is a PhD student at the Institute of Nuclear and Particle Physics. He has graduated from the Physics department of the National and Kapodistrian University of Athens. He obtained his MSc Diploma on “Nuclear and Particle Physics” from the same department with his Msc Thesis about Supersymmetric Dark Matter: “Indirect Detection of Dark Matter through Neutrino signals coming from the Sun”.
His scientific interests include Neutrino detection, Supersymmetry, Astroparticle Physics and Dark Matter.
I am a PhD student currently working on next-to-next-to-leading order calculations (NNLO) for high energy scattering processes, in the framework of perturbative Quantum Chromodynamics. In order to test our comprehension of nature in a significant way we need the theoretical calculation of scattering amplitudes in an accuracy similar to the experimental one. The high-luminosity LHC at CERN will require the most precise theoretical predictions for the scattering amplitudes. NNLO and in several cases NNNLO calculations will be of paramount importance to achieve the required precision. Pursuing this ultimate goal within my dissertation I study the systematization of the way of finding the Canonical Basis of Master Integrals for a given two-loop family, and the extension of the OPP method for one-loop amplitudes to the next order.
