“…The analysis of these data also allowed a prediction of the cross section for the K − p → π 0 0 reaction in good agreement with data, without using the data of that reaction in the fit. While in all known reactions the two poles do not revert to two peaks, but only to peaks of different shapes [2,[30][31][32][33][34][35][36][37][38][39], the new data on electroproduction [40], with two visible peaks around 1368 and 1423 MeV, have been an unexpected surprise. The lower pole is also broader than the higher one, as extracted from the photoproduction data in [1].…”

Isospin 0 and 1 resonances fromπΣphotoproduction data

Recently we presented a successful strategy to extract the position of the two (1405) poles from experimental photoproduction data on the γp → K + π 0 0 reaction at Jefferson Lab. Following a similar strategy, we extend the previous method to incorporate also the isospin 1 component which allows us to consider in addition the experimental data on γp → K + π ± ∓ . The idea is based on considering a production mechanism as model independent as possible and implementing the final state interaction of the final meson-baryon pair based on small modifications of the unitary chiral perturbation theory amplitudes. Good fits to the data are obtained with this procedure, by means of which we can also predict the cross sections for the K − p →KN, π , and π reactions for the different charge channels. Besides the two poles found for the (1405) resonance, we discuss the possible existence of an isospin 1 resonance in the vicinity of theKN threshold.

In this work we investigate different possible interpretations of the (1405) signal associated with the production of the (1405) in p + p reactions at 3.5 GeV beam kinetic energy measured by the HADES collaboration. We study the influence of interference effects between the (1405) resonance and the nonresonant background. The two poles nature of the (1405), which is supported by most of the theoretical models, is also discussed with emphasis on the relative contributions of the two complex poles to the formation of the resonance in p + p reactions.

“…From the experimental viewpoint, the Λ(1405) has been observed in the low energy exclusive reactions. Traditionally, the kaon and pion beams have been used [70,71], and several highstatistics data are recently available in photoproductions by the LEPS collaboration [72] and the CLAS collaboration [73,74], and in the proton-proton collisions by the HADES collaboration [75]. It is remarkable that the spin-parity 1/2 − is experimentally determined by the CLAS collaboration [76].…”

Exotic hadrons from heavy ion collisions

High energy heavy ion collisions are excellent ways for producing heavy hadrons and composite particles, including the light (anti)nuclei. With upgraded detectors at the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC), it has become possible to measure hadrons beyond their ground states. Therefore, heavy ion collisions provide a new method for studying exotic hadrons that are either molecular states made of various hadrons or compact system consisting of multiquarks. Because their structures are related to the fundamental properties of Quantum Chromodynamics (QCD), studying exotic hadrons is currently one of the most active areas of research in hadron physics. Experiments carried out at various accelerator facilities have indicated that some exotic hadrons may have already been produced. The present review is a summary of the current understanding of a selected set of exotic particle candidates that can be potentially measured in heavy ion collisions. It also includes discussions on the production of resonances, exotics and hadronic molecular states in these collisions based on the coalescence model and the statistical model. A more detailed discussion is given on the results from these models, leading to the conclusion that the yield of a hadron that is a compact multiquark state is typically an order of magnitude smaller than if it is an excited hadronic state with normal quark numbers or a loosely bound hadronic molecule. Attention is also given to some of the proposed heavy exotic hadrons that could be produced with sufficient abundance in heavy ion collisions because of the significant numbers of charm and bottom quarks that are produced at RHIC and even larger numbers at LHC, making it possible to study them in these experiments. Further included in the discussion are the general formalism for the coalescence model that involves resonance particles and its implication on the present estimated yield for resonance production. 1 arXiv:1702.00486v1 [nucl-th] 1 Feb 2017Finally, a review is given on recent studies to constrain the hadron-hadron interaction through correlation measurements in heavy ion collisions and their implications on the interpretation and the possible existence of exotic states in hadronic interactions.
