Is the Pentaquark the Only Justification for Research on KN Physics ?
P. M. Gensini, R. Hurtado, Y. N. Srivastava +1
The talk is intended to motivate the use of DANE--2 running at the peak as an intense, clean source of low--momentum charged and neutral kaons. It covers a few open problems…
Higgs boson decay in the large N limit
John Morales, R. Martinez, Rodolfo A. Diaz +1
The Equivalence Theorem is commonly used to calculate perturbatively amplitudes involving gauge bosons at energy scales higher than gauge boson masses. However, when the scalar sec…
Can large fermion chemical potentials suppress the electroweak phase transition ?
Carlos Quimbay, John Morales, Rafael Hurtado
We calculate the critical temperature ) of the electroweak phase transition in the minimal standard model considering simultaneously temperature () and fermion chemical po…
Dispersion relations at finite temperature and density for nucleons and pions
Rafael Hurtado, John Morales, Carlos Quimbay
We calculate the nucleonic and pionic dispersion relations at finite temperature T and non-vanishing chemical potentials in the context of an effective chiral theory that d…
Dispersion relations in Kbar N - pi Y coupled channel analyses
Paolo M. Gensini, Rafael Hurtado, Galileo Violini
Rapidly convergent, unsubtracted dispersion relations have been used to test coupled channel analyses of low-energy S = -1 meson-baryon pi Y --> pi Y' channels. We conclude that th…
What Do We Know about Low--Energy Interactions? Need and Possibilities of New Experiments at DANE
P. M. Gensini, R. Hurtado, G. Violini
We present results from a dispersion--relation investigation on a coupled--channel analysis of --initiated processes in the low-- and intermediate--energy region. The ana…
