New Physics at the Tevatron and the LHC May Relate to Dark Matter Visible in UHE Cosmic Rays [article]

Alan. R. White
2011 arXiv   pre-print
In this paper it is argued that a number of experimental phenomena in Cosmic Ray and hadron collider physics can be interpreted as evidence for the sextet sector.  ...  A two flavor color sextet quark sector added to QCD yields the uniquely unitary Critical Pomeron at high energy while also producing electroweak symmetry breaking.  ...  As a consequence it has not been included in the models used for shower analysis.  ...

Chasing Individuation: Mathematical Description of Physical Systems [article]

Federico Zalamea
2016 arXiv   pre-print
Moreover, this dissertation shows the existence of a tension between a certain "abstract way" of conceiving mathematical structures, used in the practice of mathematical physics, and the necessary capacity  ...  The "Chase for Individuation" is the analysis of different mathematical techniques which attempt to overcome this tension. In particular, we discuss how group theory furnishes a partial solution.  ...  The mathematical object D(S) is then perceived as a formal framework in which it is possible to develop certain techniques, useful for the theoretical analysis of physical systems.  ...
