Looking for a theory of faster-than-light particles
Several principal aspects of a theoretical approach to the theory of
faster-than-light particles (tachyons) are considered in this note. They
concern the resolution of such problems of tachyon theory as the causality
violation by tachyons, the stability of the tachyon vacuum, and the stability
of ordinary particles against the spontaneous emission of tachyons, i.e. the
problems which are generally used as arguments against the possibility of such
particles. It is demonstrated that all these arguments contain nontrivial
loopholes which undermine their validity. A demand for a consistent tachyon
theory is formulated, and several ideas for its construction are suggested.Comment: 41 pages, 5 figure
Connection between soft and hard probes of small collision systems at RHIC and LHC
The expected connections between signatures in the soft and hard sectors of
small collision systems, and the status of experimental attempts to identify
them, are discussed. These proceedings summarize the talk as given at the
International Symposium on Multi-Particle Dynamics in September 2019 in Santa
Fe, NM (ISMD19). As such, the choice of content and focus are selective and not
intended to be comprehensive.Comment: 6 pages, 3 figures, proceedings of the ISMD1
SOLVABILITY EXPLORATION OF SEGMENTATION PROBLEM WITH LINEAR CONVOLUTION ALGORITHMS
The paper is dedicated to decidability exploration of market segmentation problem with the help of linear convolution algorithms. Mathematical formulation of this problem represents interval task of bipartite graph cover by stars. Vertices of the first partition correspond to types of commodities, vertices of the second – to customers groups. Appropriate method is offered for interval problem reduction to two-criterion task that has one implemented linear convolution algorithm. Unsolvability with the help of linear convolution algorithm of multicriterion, and consequently interval, market segmentation problem is proved
