Observation of a Narrow Pentaquark State, ${P}_{c}(4312{)}^{+}$, and of the TwoPeak Structure of the ${P}_{c}(4450{)}^{+}$
/ Aaij, R. ; Abellán Beteta, C. ; Adeva, B. ; Adinolfi, M. ; et al
A narrow pentaquark state, ${P}_{c}(4312{)}^{+}$, decaying to $J/\psi p$, is discovered with a statistical significance of $7.3\sigma $ in a data sample of ${\Lambda}_{b}^{0}\to J/\psi p{K}^{}$ decays, which is an order of magnitude larger than that previously analyzed by the LHCb Collaboration.

Search for a Stable SixQuark State at BABAR
/ Lees, J. P. ; Poireau, V. ; Tisserand, V. ; Grauges, E. ; et al
Recent investigations have suggested that the sixquark combination $uuddss$ could be a deeply bound state ($S$) that has eluded detection so far, and a potential dark matter candidate. [...]

Study of the reactions ${e}^{+}{e}^{}\to {\pi}^{+}{\pi}^{}{\pi}^{0}{\pi}^{0}{\pi}^{0}$ and ${\pi}^{+}{\pi}^{}{\pi}^{0}{\pi}^{0}\eta $ at centerofmass energies from threshold to 4.35 GeV using initialstate radiation

First Evidence for $\mathrm{cos}2\beta >0$ and Resolution of the CabibboKobayashiMaskawa QuarkMixing Unitarity Triangle Ambiguity
/ Adachi, I. ; Adye, T. ; Ahmed, H. ; Ahn, J. K. ; et al
We present first evidence that the cosine of the $CP$violating weak phase $2\beta $ is positive, and hence exclude trigonometric multifold solutions of the CabibboKobayashiMaskawa (CKM) Unitarity Triangle using a timedependent Dalitz plot analysis of ${B}^{0}\to {D}^{(*)}{h}^{0}$ with $D\to {K}_{S}^{0}{\pi}^{+}{\pi}^{}$ decays, where ${h}^{0}\in \{{\pi}^{0},\eta ,\omega \}$ denotes a light unflavored and neutral hadron.
