The survey of planetary nebulae in Andromeda (M31) VII. Predictions of a major merger simulation model compared with chemodynamical data of the disc and inner halo substructures

C. Tsakonas, M. Arnaboldi, S. Bhattacharya +5

The nearest giant spiral, M31, exhibits a kinematically hot stellar disc, a global star formation episode ~2-4 Gyr ago, and conspicuous substructures in its stellar halo that are s…

Observation of double J/ meson production in pPb collisions at = 8.16 TeV

CMS Collaboration

The first observation of the concurrent production of two J/ mesons in proton-nucleus collisions is presented. The analysis is based on a proton-lead (pPb) data sample recorded…

Measurement of the polarizations of prompt and non-prompt J/ and (2S) mesons produced in pp collisions at = 13 TeV

CMS Collaboration

The polarizations of prompt and non-prompt J and (2S) mesons are measured in proton-proton collisions at = 13 TeV, using data samples collected by the CMS experim…
