HOW LIGHT THE LEPTON FLAVOR CHANGING GAUGE BOSONS CAN BE

How light the lepton flavor changing gauge bosons can be

Abstract Spontaneous breaking of inter-family (horizontal) gauge symmetries can be toothbrush at the origin of the mass hierarchy between the fermion families.The corresponding gauge bosons have flavor-nondiagonal couplings which generically induce the flavor changing phenomena, and this puts strong lower limits on the flavor symmetry breaking scal

Densification and Combustion of Cherry Stones

The aim of the presented research was to determine the suitability of cherry stones as a solid fuel.Mixtures of cherry stones with the addition of 10%, 15%, and 20% rye bran as a Coveralls binder were subjected to the pressure agglomeration process in a rotary matrix working system (170, 220, and 270 rpm).The density of pellets, their kinetic durab

Semi-universal geo-crack detection by machine learning

Introduction: Cracks are a key feature that determines the structural integrity of rocks, and their angular distribution can be used to determine the local or regional stress patterns.The temporal growth of cracks can be monitored in order to predict impending failures of materials or structures such as a weakened dam.Thus, cracks and their spatial
