Big Bang Nucleosynthesis and the Neutrino-Extended Standard Model Effective Field Theory

Pieter Braat, Jordy de Vries, Jelle Groot +2

We study the impact of light GeV-scale heavy neutral leptons (HNLs) on Big Bang nucleosynthesis (BBN) in the neutrino-extended Standard Model Effective Field Theory ( $I^½$ SMEFT). We…

Measurement of exclusive $J / I ¨ $ and $I ¨ (2 S)$ production at $s = 13$ TeV

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1075

Measurements are presented of the cross-section for the central exclusive production of $J / I ¨ \to I^¼^{+} I^¼^{-}$ and $I ¨ (2 S) \to I^¼^{+} I^¼^{-}$ processes in proton-proton collisions at $\sqrt{s}…
