Boson to boson: What if two divine particles collided?

As far as we know, there are four forces in physics that set the world in motion: the strong nuclear interaction, the electromagnetic interaction, the weak nuclear interaction, and the gravitational interaction. The Standard Model perfectly describes the interactions between the first three.

    When and how we see infrared: Researchers describe brightness of seeing 'invisible' photons

    There are situations in which the human eye captures normally invisible infrared radiation. Scientists from Warsaw's ICTER have developed a method for assessing the brightness obtained in this so-called two-photon vision. In their opinion, this opens up new perspectives for ophthalmological diagnostics and virtual reality.

    Monogamy is not fundamental feature of quantum physics, Polish researchers find

    Monogamy is not a fundamental feature of nature at all - at least not when it comes to quantum non-locality, shows Polish research published in the prestigious PNAS. Apart from being a huge surprise for physicists, these results have significant consequences for communication, security and testing of quantum networks.

    Dance of matter and antimatter. New Polish idea for tomography biomarker

    Annihilation (mutual destruction of matter and antimatter) has long been used in PET scanners. Now an interdisciplinary team from Poland has developed a lightweight and cheap new-generation tomography scanner - J-PET, which measures the rate of this annihilation in various tissues. This new biomarker makes it possible to create brain maps with completely new information, e.g. about glioma.

    Physicists produce heaviest exotic antimatter nucleus to date - antihyperhydrogen-4

    An antimatter hypernucleus consisting of four aniparticles has been detected at the American RHIC (Relativistic Heavy Ion Collider). Antihyperhydrogen-4 is the heaviest exotic nuclear structure in the world of antimatter discovered so far. Polish scientists also participated in the STAR experiment.

    Bose-Einstein condensation of photons in laser

    Scientists from Wrocław University of Science and Technology offer a new perspective of the principles of operation of semiconductor lasers. The results of their important laser physics discovery have just been published in the journal Nature Photonics.

    Tornado in a box: Twisted Polish idea for quantum memory

    Physicists from Warsaw have built a trap for 'quantum tornadoes' - single quantum vortices that appear in superconductors. Thanks to the world's fastest thermometer of their own design, they have studied these vortices and determined how to control them. Now scientists propose to use this idea as memory in quantum computers.

    Maps can be deceiving and have serious consequences, says mathematician

    Just as statistics or graphs can distort reality, so can the maps we use every day. However, if you learn the mathematics hidden behind maps, you will not be so easily led astray, says mathematician Dr. Paulina Rowińska.

  • The Higgs boson (blue) may form as a result of the interaction of gluons (yellow) during proton collisions. Protons consist of two up quarks (red) and one down quark (purple), bound by gluons so strongly that in the forming sea of virtual particles (gray) more massive quarks and antiquarks, for example beauty quarks, may appear, and their presence also affects the Higgs boson birth process.

    After 12 years of research, Higgs still does not reveal elements of new physics

    After 12 years of detailed research into the properties of the Higgs boson, there is no indication that it will be possible to extend the Standard Model with elements of new physics - new analyses involving Polish scientists show.
