Abstract
The Jagiellonian Positron Emission Tomograph (J-PET) is a novel device being developed at Jagiellonian University in Krakow, Poland based on organic scintillators. J-PET is an axially symmetric (M. Mohammed) has been affiliated to affiliation 6. Please check if correct, otherwise, provide the correct affiliation.and high acceptance scanner that can be used as a multi-purpose detector system. It is well suited to pursue tests of discrete symmetries in decays of positronium in addition to medical imaging. J-PET enables the measurement of both momenta and the polarization vectors of annihilation photons. The latter is a unique feature of the J-PET detector which allows the study of time reversal symmetry violation operator which can be constructed solely from the annihilation photons momenta before and after the scattering in the detector.
Highlights
Testing whether Nature is invariant under time reversal is one of the most curious challenges in physics
The novelty of the method is constituted by using of the discrete symmetry odd-operators constructed with the polarization ( i) of the annihilation photons originating from the decay of o-Ps atoms, as listed in Table 2 [8]
The Jagiellonian Positron Emission Tomograph (J-Positron emission tomography (PET)) analysis framework stands as a backbone to analyze the collected data to produce the results presented in this article [15]
Summary
Testing whether Nature is invariant under time reversal is one of the most curious challenges in physics. One can reverse the direction of motion in space, one cannot.
