At the Technical University of Georgia, a well-known physicist, one of the leaders of the CMS collaboration of the European Organization for Nuclear Research (CERN), Professor Tiziano Camporesi gave a public lecture – “True Measurements... False Discoveries” to the scientific-academic circles and students of GTU.

The public lecture of the CERN scientist was attended by GTU Vice Rector, Associate Professor Tamar Tsereteli, GTU Deputy Rector in the field of Science, Professor Tamar Lominadze, students of the Faculty of Informatics and Management Systems, professors and teachers of the Department of Engineering Physics, the director of the Institute of Quantum Physics and Engineering Technologies of GTU, advisor to the rector, head of the CERN-LHC group, professor Zviad Tsamalaidze, scientists of the institute, young researchers, as well as heads of GTU scientific research institutes and research associates.  

As the Deputy Rector of the Technical University of Georgia, Professor Tamar Lominadze noted, doctor and Professor Tiziano Camporesi is currently one of the leaders of the CERN/CMS collaboration and a former spokesperson of the CERN/CMS collaboration, has been engaged in important research in the field of nuclear and particle physics for many years. According to her, Tiziano Camporesi is not only a visiting professor of the Technical University of Georgia but also an honorary doctorate of the university and an elected member of the Supervisory Board of GTU, together with famous Georgian, European, Asian, and American scientists. As Tamar Lominadze said: “The CERN-LHC group of scientists of the Technical University of Georgia and young researchers, under the leadership of Professor Zviad Tsamalaidze, have been working effectively for several years on such sub-detectors of the CMS experiment, such as the muon spectrometer (RPC) detectors and the hadronic calorimeter (HCAL), and are actively involved in the current sub-detectors in key tasks. In addition, they participate both in the optimization and analysis of the CMSSW platform of the main software, as well as in the geometric analysis of the CMS experiment GEANT4”.

According to the director of the Institute of Quantum Physics and Engineering Technologies of GTU, Professor Zviad Tsmalaidze, the public lecture, in which the many years of experience and the most important scientific observations of Professor Tiziano Camporesi and CERN scientists in the direction of high energy physics and the CERN/CMS experiment is accumulated, for the students and researchers of the Technical University of Georgia is interesting in many ways.

Tiziano Camporesi noted that high energy physics (HEP) scientists have developed a strategy for discovering a new phenomenon and the criteria for its disclosure. 

“If we look at HEP’s history, we can see how likely mistakes are made, and which opportunities are there to avoid them. Understanding the universe and its behavior constantly requires the creation of improved, more complete instruments and measuring devices, which play a major role in the ongoing experiments at colliders. The complexity of the tools used in modern research, their meticulous sophistication, and the highest accuracy of measurements require extremely strict and accurate approaches so that the results of scientific research meet expectations as much as possible. Scientists from different countries, who are members of the CERN collaborations, have developed a kind of deep approach - a strategy for the discovery of new phenomena. I will try to provide you with information about the criteria we use to manifest a “discovery” to avoid the mistakes of the past as much as possible. My public lecture is an attempt to share all this,” said Tiziano Camporesi.

In a public lecture, the CERN scientist shared examples from the history of HEP with GTU students and professors, talked about important discoveries, data probability, the “5 sigma” criterion and its modern application, systematic errors, the inadequacy of certain models, subconscious “expectations” in science, about the intersection of theory and practice, and global questions that remain unanswered, and about future scientific plans.

After the public lecture, a discussion and dialogues were held, in which the director of the Institute of Quantum Physics and Engineering Technologies of GTU, professor Zviad Tsamalaidze, scientists of the institute, young researchers, and students participated.
