Final states with tau leptons at the Belle (II) experiment are a very promising test ground to search for lepton flavor violation and dark sector candidates. Recent searches for lepton flavor violation and dark sector candidates with data collected by the Belle (II) are presented. Future projections of expected sensitivity are also discussed. Beam polarization upgrade at SuperKEKB/Belle (II)...
Borexino recently reported the first experimental evidence for a CNO neutrino. Since this process accounts for only about 1% of the Sun’s total energy production, the associated neutrino flux is remarkably low compared to that of the pp chain, the dominant hydrogen-burning process. This experimental evidence for the existence of CNO neutrinos was obtained using a highly radio-pure Borexino...
It has been know that Quantum Mechanics allows a strong and bizarre correlation among particles, called entanglement, that is not possible in any alternative theories that are local and real. In those local-real theories, correlations among particles must satisfy Bell inequalities, while Quantum Mechanics can violate them.
The entanglement and Bell inequalities are therefore thought of the...
Ultra-peripheral collisions (UPC) of heavy ions provide unique opportunity to study vector meson (VM) photoproduction in ALICE. Analyses of different species of VMs address the gluon saturation and nuclear shadowing. Light vector mesons offer the opportunity to study the approach to the black-disc limit of QCD. Measurement of the heavy vector meson photoproduction cross section as a function...
The detection of an electric dipole moment (EDM) of elementary particles can shed light on two nagging questions of contemporary particle physics and cosmology. These are the excess of matter over antimatter, which is related to the strength of the CP symmetry violation, and the composition of dark matter (DM), which comprises a large fraction of the energy content of the Universe. In order to...
There are experimentally observed long-range e.g. Coulomb-like interactions for topological defects in liquid crystals, suggesting investigation how far can we take this resemblance with particle physics. I will discuss postulating skyrmion-like Lagrangian to get electromagnetism for their effective dynamics, interpreting filed curvature as electric field - making Gauss law count (quantized)...
A brief introduction to the CERN accelerator complex, as seen from a beam instrumentation perspective, will be presented. In addition, a deeper look into the physics and challenges of some traditional intensity, position and Schottky instruments will also be discussed.
D’où venons nous? Que sommes nous? Où allons nous? Where Do We Come From? What Are We? Where Are We Going? This is a good metaphorical summary of the initial design, upgrade I and upgrade II silicon detectors for LHCb – the precision experiment at LHC. The first LHCb era, after LHC Run 1 and Run 2, finished in 2018, and the second one began immediately with an ambitious upgrade I project that...
A main goal of the HADES (High Acceptance Di-Electron Spectrometer) experiment at GSI is to study medium effects in e+e- production in heavy-ion reactions in the SIS-18 energy range (1-4 GeV/nucleon). Its excellent particle identification capabilities allowed for a systematic investigation of dielectron, strange particles and pion production in pion, proton, deuteron or heavy-ion induced...
The National Center for Synchrotron Radiation SOLARIS in Cracow is the only operator of a synchrotron radiation source in Poland and a premier center in the world. It provides beam time both for scientific and commercial users, in a broad range of topics from material sciences to biological and pharmaceutical applications. Currently we operate six experimental beam lines and three are under...
My research aims at solving and broadening the view on current problems related to ultrarelativistic heavy-ion collisions. These results form integral to ongoing and planned experiments at CERN, the European Organization for Nuclear Research.
I will present the elementary and nuclear cross section for electromagnetic production of particles that result from $\gamma\gamma$-fusion or...
ATLAS is one of the two general purpose experiments operating at LHC. Besides it’s main goals, the Higgs boson studies, searches for new physics at energy frontier and precise test of the Standard Model, ATLAS is also perfectly suited for heavy-ion physics. This talk presents an overview of ATLAS measurements in heavy-ion collision systems. These include multiple measurements of jet production...
In this seminar I will revise the principles of tomographic reconstruction in nuclear imaging, not only for nuclear medicine applications. Emphasis will be placed on unconventional imaging concepts for preclinical research, diagnosis and particle therapy monitoring. Some of the related challenges (low-count data, limited-angle acquisition, etc.) and possible solutions will be presented.
W ostatnich latach technologia akceleratorowej spektrometrii masowej (Accelerator Mass Spectrometry, AMS) poskutkowała możliwością zakupu kompleksowej aparatury badawczej, umożliwiającej prowadzenie badań na zupełnie nowych poziomach w różnych dziedzinach nauki. Podczas seminarium przedstawiony zostanie raport, którego celem było zebranie informacji na temat możliwości powstania laboratorium...
