Axioms for the coincidence index of maps between manifolds of the same dimension
We study the coincidence theory of maps between two manifolds of the same
dimension from an axiomatic viewpoint. First we look at coincidences of maps
between manifolds where one of the maps is orientation true, and give a set of
axioms such that characterizes the local index (which is an integer valued
function). Then we consider coincidence theory for arbitrary pairs of maps
between two manifolds. Similarly we provide a set of axioms which characterize
the local index, which in this case is a function with values in . We also show in each setting that the group of values for the index
(either or ) is determined by the axioms.
Finally, for the general case of coincidence theory for arbitrary pairs of
maps between two manifolds we provide a set of axioms which charaterize the
local Reidemeister trace which is an element of an abelian group which depends
on the pair of functions. These results extend known results for coincidences
between orientable differentiable manifolds.Comment: 29 page
Probing the in interactions at the LHC
The production of in the interactions that occur in
proton-proton, proton-nucleus and nucleus-nucleus collisions at the CERN Large
Hadron Collider (LHC) is investigated and predictions for the kinematical
ranges probed by the ALICE and LHCb Collaborations are presented. We focus on
the process, which have been measured
by the Belle Collaboration, and present parameter free predictions for the
total cross sections at the LHC energies. Our results demonstrate that the
experimental study of this process is feasible and can be used to confirm or
not the existence of the state. Finally, for completeness, we present
predictions for the production of the state in the process and show that this exotic state can also be
probed in interactions at the LHC.Comment: 5 pages, 2 figures, 2 table
