Elastic Form Factors in Point-form Approach

Using the point-form approach to relativistic quantum mechanics, a covariant framework is presented for the calculation of proton and neutron electromagnetic form factors. Results for charge radii, magnetic moments, and electric as well as magnetic form factors are produced using the wave functions obtained in the socalled Goldstone-boson-exchange constituent quark model. All the predictions ar...

proficiency level and factors fostering reticence in efl learners

according to cheng (1999), in recent esl/efl literature, asian (especially east asian) learners of english as a foreign/second language have been arguably reported as reticent and passive learners. the most common allegations are that these students are reluctant to participate in classroom discourse; they are unwilling to give responses; they do not ask questions; and they are passive and over...

Worldsheet Scattering in AdS 5 × S 5

We calculate the S-matrix in the gauge-fixed sigma-model on AdS 5 × S 5 to the leading order in perturbation theory, and analyze how supersymmetry is realized on the scattering states. A mild nonlocality of the supercharges implies that their action on multi-particle states does not follow the Leibniz rule, which is replaced by a nontrivial coproduct. The plane wave symmetry algebra is thus nat...

Modelling form factors in HQET

We present a simple and straightforward method for relating the form factors in HQET, as defined by the covariant trace formalism, to the overlaps of the rest frame wave functions of the light degrees of freedom. We also point out several inconsistencies present in recent calculations of the radiative rare B decays, and also show how these can be fixed even within the framework of the non-relat...

Baryon Form Factors in QCD

The form factors of baryons have long been studied in electron scattering, and now we are here to discuss new opportunities that can come from an e+e− collider at moderate energies where exclusive cross sections may be measured. One can foresee measurements of the form factors of baryons in the timelike region. The richness of these measurements should be clear. We can in principle measure the ...
