We are curious of the world. We like to boast about it. And we like to leave a trace: I WAS HERE is what we write in different places around the world, or take photos there, which is less invasive for the landscape.<\/p>\n

We also were! Where? Enjoy reading the scientific travel series.<\/p>\n<\/div>\r\n <\/div>\r\n <\/div>[\/vc_column][vc_column width=”1\/4″]\r\n

CERN one year later<\/strong><\/p>\n

\u2018When I got my Master\u2019s degree in sociology, I told myself, \u2018Marta, it\u2019s time to settle down, get a job, a house, a family, a cat, water your flowers on a regular basis…\u2019 As it usually is with me, I did quite the opposite and decided to study physics,\u2019 the doctoral student Marta Urbaniak wrote one year ago. Back then, she was still before her first working day at CERN, and she couldn\u2019t wait to go there. What are her post-CERN impressions?<\/em><\/p>\n

Speed close to the speed of light, over 20 detectors, over 200 people from all over the world conducting analyses and building the detection system, studying the production of strangeness and open charm, studies on the state of matter where quarks are spontaneously released; to see it all and work in the hall where it all takes place is really impressive.<\/p>\n

I joined the NA61\/SHINE experiment carried out at CERN during my first year of studies at the Doctoral School of the University of Silesia. It was my dream to come to the place where the studies are happening and which I\u2019d heard so much about from my fellow team members. The dream came true pretty quickly, as soon as the second year of my studies.<\/p>\n

One of the main goals of the experiment was to examine the state of matter which was present at the initial stage of the universe existence: quark-gluon plasma. This is an example of an exceptional state when quarks and gluons move freely, which is absent under normal conditions. Thanks to CERN infrastructure, we are able to create such conditions in our experiment, whereas the precise measurement system helps us search for phase transition signals. One of such observables is changes in the production of particles that contain strange and\/or charm quarks.<\/p>\n

The experiment also involves unique measurements allowing for a more precise measurement in experiments examining the oscillations of neutrinos and studies necessary for the development of galactic cosmic-ray (GCR) propagation models.<\/p>\n

This last theme is particularly important for me, because it is related to the subject of my PhD thesis. A very important element of galactic cosmic-ray (GCR) propagation models is the values of cross sections per the process of fragmentation (division) of light and medium-weight atomic nuclei during collision with intergalactic matter, which we measure in our experiment. The development of models and measurements of cosmic ray streaming in such experiments as AMS or PAMELA allows us to find a response to the following questions: what physical processes accelerate particles to such high energy? What physical conditions are present in the objects of particle acceleration? To conduct all these measurements, we need three main elements:<\/p>\n
