DANSS is a one cubic meter highly segmented solid scintillator detector. It consists of 2500 scintillator strips (100x4x1 cm3), covered with gadolinium loaded reflective coating and read out with SiPMs via wave length shifting fibers. Groups of 50 strips are also read out by conventional PMTs. The detector does not contain dangerous liquids and therefore has no safety restrictions on location clos ... More

The methods of the fractal geometry are applied to the particles distribution for the multiparticle events from heavy-ion collisions (HIC). It is shown that such kind of analyses provides a possibility to distinguish between different equation of state in hydrodynamic models of HIC. Implementation of these methods could reveal many other features of the physics for particle production.

Session: Introduction
Presented by Prof. Mikhail ITKIS on 25 Sep 2018 at 09:05
We suggest a renewed view on non-renormalizable interactions treated perturba- tively within a kinematically dependent renormalization procedure. It is based on the usual BPHZ R-operation which is equally applicable to any local QFT indepen- dently whether it is renormalizable or not. The key point is that the renormalization constant becomes the function of kinematical variables acting as an oper ... More

Until 2010, the accepted value for the proton charge radius was 0.8768 ± 0.0069 fm. This was determined from both electron-proton scattering and electron hydrogen spectroscopy. In 2010 the Proton Radius Puzzle (PRP) began when the CREMA Collaboration determined the proton radius via muonic hydrogen spectroscopy, yielding a value 7σ smaller that the previous result (0.84184 ± 0.00067 fm). One p ... More
