Including virtual photons in strong interactions
نویسنده
چکیده
In the perturbative field-theoretical models we investigate the inclusion of the electromagnetic interactions into the purely strong theory that describes hadronic processes. In particular, we study the convention for splitting electromagnetic and strong interactions and the ambiguity of such a splitting. The issue of the interpretation of the parameters of the low-energy effective field theory in the presence of electromagnetic interactions is addressed, as well as the scale and gauge dependence of the effective theory couplings. We hope, that the results of these studies are relevant for the electromagnetic sector of ChPT. PACS. 13.40.Ks, 13.40.Dk, 11.30.Rd, 11.10.Hi

Background: Considering the negative impact of social phobia on social interactions and the positive effect of communication skills training on this condition, the literature on the training methods that would be suitable for people with this condition seems deficient. This study aimed to compare the effect of communication skills training delivered via workshop and virtual met...
متن کاملInterpreting virtual photon interactions in terms of parton distribution functions
Interactions of virtual photons are analyzed in terms of photon structure. It is argued that the concept of parton distribution functions is phenomenologically very useful even for highly virtual photons involved in hard collisions. The role of longitudinal photons for proper interpretation of jet cross–section in the region of moderate virtualities accessible at HERA is investigated.

متن کاملElectromagnetic corrections in hadronic processes
In quantum field theory, the splitting of the Hamiltonian into a strong and an electromagnetic part cannot be performed in a unique manner. In the present article, we propose a convention for disentangling these two effects: one matches the parameters of two theories – with and without electromagnetic interactions – at a given scale μ1, referred to as the matching scale. This method enables one...
