New Quadratic Baryon Mass Relations
By assuming the existence of (quasi)-linear baryon Regge trajectories, we derive new quadratic Gell-Mann–Okubo type baryon mass relations. These relations are used to predict the masses of the charmed baryons absent from the Baryon Summary Table so far, in good agreement with the predictions of many other approaches.

متن کاملPion and Kaon Polarizabilities and Radiative Transitions
CERN COMPASS plans measurements of γπ and γK interactions using 50-280 GeV pion (kaon) beams and a virtual photon target. Pion (kaon) polarizabilities and radiative transitions will be measured via Primakoff effect reactions such as πγ → π ′ γ and πγ → meson. The former can test a precise prediction of chiral symmetry; the latter for πγ → a1(1260) is important for understanding the polarizabili...
متن کاملThe Pion and Kaon Electromagnetic Form Factors
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 pi...
متن کاملKaon and pion production at CBM energies
It has been argued that a strangeness enhancement in heavy ion collisions might be an indirect signal for the quark-gluon plasma [1]. This enhancement should be most easily seen in the most abundant strange particles, the kaons. Experiments at the AGS and SPS indeed found a maximum in the K/π at about 30 GeV [2]. In [3] the authors presented an excitation function of the K/π ratio at these ener...
