报告题目：

Prospects for pentaquark searches in photoproduction

报告摘要：

In 2015, the LHCb has reported two resonance-like structures in the J/psi p invariant masses, compatible with hidden-charm pentaquarks. Thereafter, several works have proposed the search and study of these resonances in J/psi p photoproduction, which would provide a confirmation of the resonant nature of the structures. In this talk, I give an overview on the theoretical and experimental status to this endeavour.

The feasibility of detecting the pentaquarks is discussed, e.g. in the measurements that have been approved for the several Halls at JLab. Theoretical studies are introduced, which give estimates to the sensitivity of the signal for different observables and angular settings, and are based on global fits to world J/psi photoproduction data. I show the results of ongoing experiments and theoretical studies made, and comment on those planned in the near future.

报告人简介：

Astrid Nathalie Hiller Blin did her Master degree in Tübingen, Germany, and her PhD in Valencia, Spain, focusing on baryon chiral perturbation theory. In that frame, she studied the electromagnetic properties and interactions of light and heavy baryons. Currently, she has a Postdoc position in Mainz, Germany, in the group of Prof. Vanderhaeghen. There, she is studying deuteron polarizabilities in a relativistic framework, as well as proton structure functions in the low and high-energy regimes.
