Using graph neural networks to reconstruct charged pion showers in the CMS High Granularity Calorimeter

M. Aamir, G. Adamov, T. Adams +568

A novel method to reconstruct the energy of hadronic showers in the CMS High Granularity Calorimeter (HGCAL) is presented. The HGCAL is a sampling calorimeter with very fine transv…

Precision measurements of the total and partial widths of the psi(2S) charmonium meson with a new complementary-scan technique in antiproton-proton annihilations

Fermilab E835 Collaboration, M. Andreotti, S. Bagnasco +46

We present new precision measurements of the psi(2S) total and partial widths from excitation curves obtained in antiproton-proton annihilations by Fermilab experiment E835 at the…

Observation of the rare $B_{s}^{0} \to I^¼^{+} I^¼^{-}$ decay from the combined analysis of CMS and LHCb data

The CMS, LHCb Collaborations, : +2807

A joint measurement is presented of the branching fractions $B_{s}^{0} \to I^¼^{+} I^¼^{-}$ and $B^{0} \to I^¼^{+} I^¼^{-}$ in proton-proton collisions at the LHC by the CMS and LHCb experiments. The data…

Radiation hardness qualification of PbWO4 scintillation crystals for the CMS Electromagnetic Calorimeter

The CMS Electromagnetic Calorimeter Group, P. Adzic, N. Almeida +267

Ensuring the radiation hardness of PbWO4 crystals was one of the main priorities during the construction of the electromagnetic calorimeter of the CMS experiment at CERN. The produ…

Measurement of the branching ratios $I ¨ ^{'} \to e^{+} e^{-}$ , $I ¨ ^{'} \to J / I ¨ I ¨ I ¨ $ and $I ¨ ^{'} \to J / I ¨ I^\cdot$

M. Andreotti, S. Bagnasco, W. Baldini +46

We have measured several branching ratios for $I ¨ ^{'}$ decay using the data collected by FNAL E835 experiment during year 2000, obtaining ${\cal B}(Ï^\prime \to e^+ e^-) = 0.00…
