Electromagnetic Form Factors of Charged and Neutral Kaons
نویسندگان
چکیده
The charged and neutral kaon form factors are calculated as a phenomenological application of the QCD Dyson-Schwinger equations. The results are compared with the pion form factor calculated in the same framework and yield FK±(Q 2) > Fπ±(Q 2) on Q2 ∈ [0, 3] GeV2; and a neutral kaon form factor that is similar in form and magnitude to the neutron charge form factor. These results are sensitive to the difference between the kaon and pion BetheSalpeter amplitude and the uand s-quark propagation characteristics. PACS NUMBERS: 13.40.Gp, 14.40.Aq, 12.38.Lg, 24.85.+p

Off-shell electromagnetic form factors of pions and kaons in chiral perturbation theory.
The off–shell electromagnetic vertex of a (pseudo–) scalar particle contains, in general, two form factors F and G which depend, in addition to the squared momentum transfer, on the invariant masses associated with the initial and final legs of the vertex. Chiral perturbation theory to one loop is used to calculate the off–shell form factors of pions and kaons. The formalism of Gasser and Leutw...
متن کاملForm factors of pion and kaon
Besides the vector meson poles in the form factors of charged pion and kaons additional intrinsic form factors of pion and kaons are found. A detailed study of the form factors of pion and kaons in both time-like and space-like regions is presented. Theory agrees well with data up to q ∼ 1.4GeV . In this study there is no adjustable parameter.
متن کاملMesons from Laser-Induced Processes in Ultra-Dense Hydrogen H(0)
Large signals of charged light mesons are observed in the laser-induced particle flux from ultra-dense hydrogen H(0) layers. The mesons are formed in such layers on metal surfaces using < 200 mJ laser pulse-energy. The time variation of the signal to metal foil collectors and the magnetic deflection to a movable pin collector are now studied. Relativistic charged particles with velocity up to 5...
متن کاملReview of the NA48 CP violation measurements with neutral and charged kaons
The main results on the CP violation measurements with neutral and charged kaons from the NA48 experiment at the CERN SPS are reviewed in this paper. The direct CP violating parameter Re(ε′/ε) has been measured by NA48 from the decay rates of neutral kaons into pion pairs. The final result, based on the data collected in 1997, 1998, 1999 and 2001, clearly established the existence of direct CP ...
متن کاملCPT and Quantum Mechanics Tests with Kaons
In this review we first discuss the theoretical motivations for possible CPT violation and deviations from ordinary quantum-mechanical behavior of field-theoretic systems in the context of an extended class of quantumgravity models. Then we proceed to a description of precision tests of CPT symmetry using mainly neutral kaons. We emphasize the possibly unique rôle of neutral meson factories in ...
