Some Predictions of Diquark Model for Hidden Charm Pentaquark Discovered at the LHCb

The LHCb has discovered two new states with preferred $J^P$ quantum numbers $3/2^-$ and $5/2^+$ from $\Lambda_b$ decays. These new states can be interpreted as hidden charm pentaquarks. It has been argued that the main features of these pentaquarks can be described by diquark model. The diquark model predicts that the $3/2^-$ and $5/2^+$ are in two separate octet multiplets of flavor $SU(3)$ and there is also an additional decuplet pentaquark multiplet. Finding the states in these multiplets can provide crucial evidence for this model. The weak decays of b-baryon to a light meson and a pentaquark can have Cabibbo allowed and suppressed decay channels. We find that in the $SU(3)$ limit, for $U$-spin related decay modes the ratio of the decay rates of Cabibbo suppressed to Cabibbo allowed decay channels is given by $|V_{cd}|^2/|V_{cs}|^2$. There are also other testable relations for b-baryon weak decays into a pentaquark and a light pseudoscalar. These relations can be used as tests for the diquark model for pentaquark.Comment: revtex, 19 pages, 3 figures. one reference added and some typos correcte

An Analysis of Religious Images in Flannery O’Connor’s Novel Wise Blood

Speaking of the Southern Women’s writing of the 20th century, Flannery O’Connor would be on the top of the list. After two novels and thirty-two stories, Flannery O’Connor, a Roman Catholic living in the American South, passed away of disease at the age of 39. Since her first novel Wise Blood which was published in 1952, her influence on literature and art has steadily been increasing—she won numerous awards in her not long life. According to McFarland, Thinking is that the realm of the Holy interpenetrates this world and affects it. It is the workings of this mystery that she was most concerned with demonstrating in her fiction. By her own explanation, the grotesquerie of her stories is directly related to her Christian perspective.Wise Blood was surely embedded in her religious views and reflected her unique writing style—the use of violence and bizarre characters, and the theological meaning, later to become its strength. Thus, the author tries to present the notions above in this paper, which is divided into five parts. The first part is an introduction of Flannery O’Connor; the second part is a brief analysis of Flannery O’Connor’s writing style. The third part focuses on the Christian cultural context of the novel, and the next part presents religious views of O’Connor through two characters: Hazel Motes and Enoch Emery. The last part is conclusion

The possible members of the 51S05^1S_0 meson nonet

The strong decays of the $5^1S_0$ $q\bar{q}$ states are evaluated in the $^3P_0$ model with two types of space wave functions. Comparing the model expectations with the experimental data for the $\pi(2360)$, $\eta(2320)$, $X(2370)$, and $X(2500)$, we suggest that the $\pi(2360)$, $\eta(2320)$, and $X(2500)$ can be assigned as the members of the $5^1S_0$ meson nonet, while the $5^1S_0$ assignment for the $X(2370)$ is not favored by its width. The $5^1S_0$ kaon is predicted to have a mass of about 2418 MeV and a width of about 163 MeV or 225 MeV.Comment: 10 pages, 5 figures, version accepted by Eur. Phys. J.
