Bridging reaction theory and nuclear structure in -Ca scattering
Viacheslav Tsaran, Francesco Marino, Sonia Bacca +2
We extend the pion-nucleus multiple-scattering framework to include detailed second-order rescattering dynamics for nuclei with non-zero isospin. To account for intermediate charge…
Exploring Baryon Resonances with Transition Generalized Parton Distributions: Status and Perspectives
Stefan Diehl, Kyungseon Joo, Kirill Semenov-Tian-Shansky +21
QCD gives rise to a rich spectrum of excited baryon states. Understanding their internal structure is important for many areas of nuclear physics, such as nuclear forces, dense mat…
A dispersive estimate of the contribution to
Oleksandra Deineka, Igor Danilkin, Marc Vanderhaeghen
A dispersive implementation of the resonance to requires the knowledge of the double-virtual -wave $γ^*γ^*\toÏη/ K K(I=1)$ amplitudes. To obtain these…
Phenomenological model for the $γ^*γ\to ηÏ^+ Ï^-$ reaction in the energy region
Xiu-Lei Ren, Igor Danilkin, Marc Vanderhaeghen
Motivated by the ongoing analysis by the BESIII Collaboration on the single-tagged reaction, we present a phenomenological study of the diphoton fusio…
Constraints for scalars and pseudoscalars from and existing colliders
Aleksandr Pustyntsev, Marc Vanderhaeghen
Scalars and pseudoscalars with masses in the MeV to GeV range are of interest in different extensions of the Standard Model. Such particles are often associated with dark matter, t…
Dispersion relation formalism for the two-photon exchange correction to elastic muon-proton scattering: elastic intermediate state
Oleksandr Tomalak, Marc Vanderhaeghen
We evaluate the two-photon exchange correction to the unpolarized cross section in the elastic muon-proton scattering within dispersion relations. One of the six independent invari…
