Dispersive analysis of the production at the CMD3 experiment and the compatibility with muon pair production measurement by KLOE2 and the pion form factor by JLAB
Dimitrios Petrellis, Vladimir Sauli
The spectral function of the charged pion form factor was extracted from two data sets. The difference between the two sets is based on the presence or absence of the recent measur…
Model selection for photoproduction within isobar model
Petr Bydžovský, Aleš Cieplý, Dimitrios Petrellis +2
We utilise an isobar model to investigate the photoproduction off a neutron in the resonance region. Except for the Born terms, we include high-spin (spin-3/2 and spin-5…
Ridge regression for minimizing the couplings of hyperon resonances in the photoproduction
Dimitrios Petrellis, Dalibor Skoupil
We employed the isobar model for investigating the photoproduction process. We paid special attention to the recent CLAS polarization data and enhanced the minimizat…
Nuclear shape / phase transitions in the N = 40, 60, 90 regions
Dimitrios Petrellis, Adam Prášek, Petr Alexa +3
We investigate the isotopes of Se, Zr, Mo and Nd in the regions with N = 40, 60 and 90, where a first-order shape / phase transition, from spherical to deformed, can be observed. T…
