Pion Scattering Revisited
M. Ruiz-Altaba, J. L. Lucio, M. Napsuciale
Chiral Ward identities lead to consistent accounting for the sigma's width in the linear sigma model's Feynman rules. Reanalysis of pion scattering data at threshold imply a mass f…

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…

Noise in Grover's Quantum Search Algorithm
B. Pablo-Norman, M. Ruiz-Altaba
Grover's quantum algorithm improves any classical search algorithm. We show how random Gaussian noise at each step of the algorithm can be modelled easily because of the exact recu…
