چکیده
We use recent data on K + → π + e + e − , together with known values for the pion form factor, to derive the kaon electromagnetic form factor for 0 < q 2 < 0.125 (GeV/c) 2. The results are then compared with predictions of the Linear σ Model, a quark-triangle model and Vector Meson Dominance. The first two models describe the data at least qualitatively, but the simple Vector Meson Dominance picture gives a detailed quantitative fit to the experimental results.

We use recent data on K + → π + e + e − , together with known values for the pion form factor, to derive experimental values for the kaon electromagnetic form factor for 0 < q 2 < 0.125 (GeV/c) 2. The results are then compared with predictions of the Vector-Meson-Dominance model, which gives a good fit to the experimental results.

Using the Nambu–Jona-Lasinio (NJL) model we study responses of the pion and kaon masses to changes in the chemical potential, ∂m ∂μ , at zero and finite chemical potential. We find that the behavior of ∂m ∂μ for the pion is quite different from that for the kaon. Our results can give a clue for future studies of ∂m ∂μ on the lattice.

We study the effect of SU (3) flavor breaking on high density quark matter. We discuss, in particular, the effect a non-zero electron chemical potential and a finite strange quark mass. We argue that these perturbations trigger pion or kaon condensation. The critical chemical potential behaves as µ e ∼ √ mm s ∆/p F and the critical strange quark mass as m s ∼ m 1/3 ∆ 2/3 , where m is the light ...
