15-19 September 2025 we are organizing the next Matter to the Deepest conference (1975-2025)!

This time in Katowice. Details are here: https://indico.if.us.edu.pl/event/21/

Our team in collaboration with scientists from the USA (University of Virginia and the Space Science Center of the University of Washington) and Germany (Max Planck Institute in Munich) published an article in the prestigious journal Progress in Particle and Nuclear Physics. The work concerns the analysis of models aimed at explaining what types of new symmetries can be used to understand the observed properties of oscillations of three types of neutrinos. The work considers so-called discrete symmetries, such as the A4 symmetry (such symmetries are used in physics, for example, to describe a diamond crystal) or more abstract symmetries based on modular groups https://en.wikipedia.org/wiki/Modular_group. These models imply the existence of new types of particles, which, in addition to describing the properties of masses and quantum mixing states of the known “flavors” of electron, muon and tau neutrinos, can also explain several cosmological observations such as matter-antimatter asymmetry in space (decays of new massive neutrinos) or the problem of dark matter (the paper considers implications derived from the interactions of spinless Higgs particles and additional fermions). The phenomenology of possible processes associated with discrete particle symmetries is very rich. Some symmetries are studied in particle colliders (e.g. LHC) or in the context of observing gravitational waves or exotic nuclear decays (e.g. neutrinoless double beta decay of nuclei). The work was carried out as part of the Opus grant of the National Science Centre “Non-standard neutrinos and CP-violating effects in the leptonic sector” (short description of the project in Polish: https://projekty.ncn.gov.pl/opisy/482538-pl.pdf). On the Polish side, the following participated in the work: Janusz Gluza (team coordinator), Szymon Zięba, Krzysztof Grzanka (PhD students), Biswajit Karmakar (postdoc), Ievgen Dubovyk, Bartosz Dziewit (assistant professors at the Faculty of Science and Technology, University of Silesia).

From 8 to 12 January 2024, Janusz Gluza participated in the XXX Cracow EPIPHANY Conference giving a talk on: “Precision Physics at High Energy Colliders and Low Energy Connections”. More extended talk on the subject has been delivered at the Indian Institute of Technology in Guwahati, India (scientific visit 1-13 February 2024).

In October 2023, we welcomed a new member to our research team – Dr. Adam Bzowski, Inspires publications

From July 30 through 6th August Janusz Gluza took part in NuFact 2022, chairing one of the plenary sessions and giving the talk “PMNS and the number of additional neutrino flavors” https://indico.fnal.gov/event/53004/contributions/243136/attachments/158351/207755/NuFact_2022.pdf. This conference was held in Snowbird, Utah, USA, and focused on neutrino physics and colliders. The twenty-third of the series of yearly international workshops started in 1999.

After serious makeup, it works again.

We were at the secondary school LO1 in Rybnik: dr Biswajit Karmakar gave a lecture „Neutrinos and secrets of our Universe” with introduction by prof. Janusz Gluza „Wielkie urządzenia, małe obiekty – krótko o fizyce cząstek elementarnych” – “Big facilities, small objects – shortly about particle physics”. Some photos: link

Together with Bhupal Dev from Washington U. and Garv Chauhan from Louvain U. we prepared a report for the Snowmass 2021 which is on future plans in particle physics. Publication is available at https://inspirehep.net/literature/2052627
