Probing the nature of the $I ¨ _{c 1} (3872)$ state using radiative decays

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1097

The radiative decays $I ¨ _{c 1} (3872) \to I ¨ (2 S) I^^{3}$ and $I ¨ _{c 1} (3872) \to J / I ¨ I^^{3}$ are used to probe the~nature of the~ $I ¨ _{c 1} (3872)$ state using proton-proton collisio…

Probing arbitrary polarized photon pairs undergoing double Compton scatterings by a dedicated MC simulator validated with experimental data

M. Bala, W. Krzemien, B. C. Hiesmayr +6

Quantum correlations in the polarization degrees of freedom of the two-photon system have been extensively studied and form our current understanding of the quantum nature of our w…

Search for charge-parity violation in semileptonically tagged $D^{0} \to K^{+} I ¨ ^{-}$ decays

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1132

An analysis of the flavour oscillations of the charmed neutral meson is presented. The ratio of $D^{0} \to K^{+} I ¨ ^{-}$ and $D^{0} \to K^{-} I ¨ ^{+}$ decay rates is measured as a f…

Measurement of the $I^_{c}^{+}$ to $D^{0}$ production cross-section ratio in peripheral PbPb collisions

LHCb collaboration

We report on a measurement of the $I^_{c}^{+}$ to $D^{0}$ production ratio in PbPb collisions at $s_{NN}$ = 5.02 TeV with the LHCb detector in the forward rapidity region $2 <y…
