Neutrino oscillation in a minimal length spacetime
Luísa Nadal Camargo, Thiago Oliveira Ferreira, Dimiter Hadjimichef +1
We investigate how neutrino oscillations are modified in a non-commutative spacetime characterized by a minimal length scale, described by the Quesne-Tkachuk algebra. By incorporat…
On the possibility of a 130 GeV gamma-ray line from annihilating singlet fermionic dark matter
T. H. Franarin, C. A. Z. Vasconcellos, D. Hadjimichef
There is evidence for a spectral line at GeV in the Fermi-LAT data that can be explained as dark mater particles annihilating into photons. We review a well known…
Glueball-glueball potential in a constituent gluon model
M. L. L. da Silva, D. Hadjimichef, C. A. Z. Vasconcellos
In this work we use a mapping technique to derive in the context of a constituent gluon model an effective Hamiltonian that involves explicit gluon degrees of freedom. We study glu…
Glueball decay in the Fock-Tani formalism
D. T. da Silva, M. L. L. da Silva, D. Hadjimichef +1
We investigate the two-meson decay modes for . In this calculation we consider this resonance as a glueball. The Fock-Tani formalism is introduced to calculate the decay…

M. L. L. da Silva, D. Hadjimichef, C. A. Z. Vasconcellos
In this work we use a mapping technique to derive in the context of a constituent gluon model an effective Hamiltonian that involves explicit gluon degrees of freedom. We study glu…
