1. First Observation of the Radiative Decay Λb0Λγ / Aaij, R. ; Abellán Beteta, C. ; Adeva, B. ; Adinolfi, M. ; et al
The radiative decay Λb0Λγ is observed for the first time using a data sample of proton-proton collisions corresponding to an integrated luminosity of 1.7 fb1 collected by the LHCb experiment at a center-of-mass energy of 13 TeV. [...]

2. Strong LHCb evidence supporting the existence of the hidden-charm molecular pentaquarks / Chen, Rui ; Sun, Zhi-Feng ; Liu, Xiang ; Zhu, Shi-Lin
On 26 March 2019, at the Rencontres de Moriond QCD conference, the LHCb Collaboration reported the observation of three new pentaquarks, namely Pc(4312), Pc(4440), and Pc(4457), which are consistent with the loosely bound molecular hidden-charm pentaquark states composed of an S-wave charmed baryon Σc and an S-wave anticharmed meson (D¯, D¯*).

3. Near-threshold D D ¯ $$ \mathrm{D}\overline{\mathrm{D}} $$ spectroscopy and observation of a new charmonium state / Aaij, R. ; Abellán Beteta, C. ; Adeva, B. ; Adinolfi, M. ; et al
Using proton-proton collision data, corresponding to an integrated luminosity of 9 fb −1 , collected with the LHCb detector between 2011 and 2018, a new narrow charmonium state, the X(3842) resonance, is observed in the decay modes X 3842 → D 0 D ¯ 0 $$ \mathrm{X}(3842)\to {D}^0{\overline{D}}^0 $$ and X(3842) → D + D − [...]
