An algebra generated by two sets of mutually orthogonal idempotents
Tatsuro Ito, Paul Terwilliger
For a field and an integer , we consider the universal associative -algebra generated by two sets of mutually orthogonal idempotents. We display four base…
Anomaly Induced Dark Matter Decay and PAMELA/ATIC Experiments
Hiroki Fukuoka, Jisuke Kubo, Daijiro Suematsu
The cosmic ray data of PAMELA/ATIC may be explained by dark matter decay with a decay rate , an energy scale which could not b…
SU(2) and SU(3) chiral perturbation theory analyses on baryon masses in 2+1 flavor lattice QCD
K. -I. Ishikawa, N. Ishizuka, T. Izubuchi +9
We investigate the quark mass dependence of baryon masses in 2+1 flavor lattice QCD using SU(3) heavy baryon chiral perturbation theory up to one-loop order. The baryon mass data u…
The augmented tridiagonal algebra
Tatsuro Ito, Paul Terwilliger
Motivated by investigations of the tridiagonal pairs of linear transformations, we introduce the augmented tridiagonal algebra . This is an infinite-dimensional ass…
Reconciliation of CDM abundance and in a radiative seesaw model
Daijiro Suematsu, Takashi Toma, Tetsuro Yoshida
We reexamine relic abundance of a singlet fermion as a CDM candidate, which contributes to the neutrino mass generation through radiative seesaw mechanism. We search solutions for…
