Electromagnetic couplings of elementary vector particles
M. Napsuciale, S. Rodriguez, E. G. Delgado-Acosta +1
On the basis of the three fundamental principles of (i) Poincaré symmetry of space time, (ii) electromagnetic gauge symmetry, and (iii) unitarity, we construct an universal Lagrang…
Electron-positron annihilation into phi f_{0}(980) and clues for a new 1^{--} resonance
M. Napsuciale, E. Oset, K. Sasaki +1
We study the e^{+}e^{-} to phi pi pi reaction for pions in an isoscalar s-wave which is dominated by loop mechanisms. For kaon loops we start from the conventional RCHPT, but use t…
High Spins Beyond Rarita-Schwinger Framework
Mariana Kirchbach, Mauro Napsuciale
We study the eigenvalue problem of the squared Pauli-Lubanski vector, W^{2}, in the Spinor-Vector representation space and derive from it that the -s(s+1)m^{2} subspace with s=3/2,…
Equations of motion as projectors and the gyromagnetic factor g_{s}=1/s} from first principles
M. Napsuciale, C. A. Vaquera-Araujo
In this work we adopt the point of view that the equations of motion satisfied by a field are just a consequence of the representation space which the field belongs to, and the dis…
phi -> pi0 pi0 gamma Decay within a U(3)x U(3) Linear Sigma Model
J. L. Lucio, M. Napsuciale
We show that therecently observed pion invariant mass distribution of the phi ->pi0 pi0 gamma decay can be satisfactorily described by the chiral U(3) X U(3) Linear Sigma Model.
The Linear Sigma Model at Work: Succesful Postdictions for Pion Scattering
J. L. Lucio, M. Napsuciale, M. Ruiz-Altaba
We enforce chiral Ward identities on the vertices of the linear sigma model to take into account the width of the scalar sigma, considered as a true physical resonance. We consider…
