When fluid flows almost as fast as light – with quantum rotation

21 June 2018

Quark-gluon plasma is formed as a result of high energy collisions of heavy ions. After a collision, for a dozen or so yoctoseconds (that's 10-24 seconds!), this most perfect of all known fluids undergoes rapid hydrodynamic expansion with velocities close to the velocity of light. An international team of scientists, associated with the IFJ PAN and the GSI Centre, has presented a new model describing these extreme flows. Interestingly, for the first time effects resulting from the fact that the particles creating the plasma carry spin, that is, quantum rotation, are taken into account.

The chances of detecting clumps in atomic nuclei are growing

14 June 2018

What do atomic nuclei really look like? Are the protons and neutrons they contain distributed chaotically? Or do they perhaps bind into alpha clusters, that is, clumps made up of two protons and two neutrons? In the case of several light nuclei, experimental confirmation of the individualism or family nature of nucleons will now be simpler thanks to predictions presented by Polish physicists from Cracow and Kielce.

CREDO: You too can help unveil the deepest puzzles of the Universe

12 June 2018

Are astrophysical phenomena occurring millions or even billions of light years from Earth responsible for some diseases? Does dark matter really exist? What is the true nature of our spacetime – is it continuous or digital? Can the exotic effects of quantum gravity be tested experimentally? Install the CREDO Detector app, become part of the largest particle detector in history and help unveil the fundamental secrets of the Universe!.

Matter-antimatter asymmetry may interfere with the detection of neutrinos

23 May 2018

From the data collected by the LHCb detector at the Large Hadron Collider, it appears that the particles known as charm mesons and their antimatter counterparts are not produced in perfectly equal proportions. Physicists from Cracow have proposed their own explanation of this phenomenon and presented predictions related to it, about consequences that are particularly interesting for high-energy neutrino astronomy.

How are hadrons born at the huge energies available in the LHC?

1 March 2018

Our world consists mainly of particles built up of three quarks bound by gluons. The process of the sticking together of quarks, called hadronisation, is still poorly understood. Physicists from the Institute of Nuclear Physics Polish Academy of Sciences in Cracow, working within the LHCb Collaboration, have obtained new information about it, thanks to the analysis of unique data collected in high-energy collisions of protons in the LHC.
