MALTA-Cz: a radiation hard full-size monolithic CMOS sensor with small electrodes on high-resistivity Czochralski substrate

Edoardo Charbon, Francesco Piro, Ashish Sharma

Depleted Monolithic Active Pixel Sensor (DMAPS) sensors developed in the Tower Semiconductor 180 nm CMOS imaging process have been designed in the context of the ATLAS ITk upgrade Phase-II at the HL-LHC and for future collider experiments. The "MALTA-Czoch ...

Measurement of lepton universality parameters in B+→K+ℓ+ℓ− and B0→K*0ℓ+ℓ− decays

A simultaneous analysis of the

B^+\to K^+\ell^+\ell^-

and

B^0\to K^{*0}\ell^+\ell^-

decays is performed to test muon-electron universality in two ranges of the square of the dilepton invariant mass,

q^2

. The measurement uses a sample of beauty meson ...

Test of Lepton Universality in b→sℓ+ℓ− Decays

The first simultaneous test of muon-electron universality using

B^{+}\rightarrow K^{+}\ell^{+}\ell^{-}

and

B^{0}\rightarrow K^{*0}\ell^{+}\ell^{-}

decays is performed, in two ranges of the dilepton invariant-mass squared,

q^{2}

. The analysis uses bea ...

Microlens-enhanced silicon photomultiplier arrays for LHCb SciFi Tracker Upgrade Ib

Olivier Schneider, Guido Haefeli, Ettore Zaffaroni, Carina Trippl

A large-scale Scintillating Fibre Tracker has been developed and constructed for the current LHCb Upgrade 1. The high radiation by fast neutrons reduces the light yield of the detector in the course of LHC Run 3, and is challenging the tracker's hit detect ...

Identification of hadronic tau lepton decays using a deep neural network

A new algorithm is presented to discriminate reconstructed hadronic decays of tau leptons (th) that originate from genuine tau leptons in the CMS detector against th candidates that originate from quark or gluon jets, electrons, or muons. The algorithm inp ...

The Forward Physics Facility at the High-Luminosity LHC

Lesya Shchutska, Yiming Li, Alexey Boyarsky, Yi Zhang, Raffaele Tito D'Agnolo, Enrico Bertuzzo, Wei Liu, Ji Hyun Kim, Zheng Wang, Jing Li, Wenjing Wu, Francesco Cerutti, Martin Bauer, Patrick Foldenauer, Karan Kumar, Saurabh Nangia, Emanuele Copello

High energy collisions at the High-Luminosity Large Hadron Collider (LHC) produce a large number of particles along the beam collision axis, outside of the acceptance of existing LHC experiments. The proposed Forward Physics Facility (FPF), to be located s ...

Description of beam instabilities in synchrotrons with wakefields and space charge forces using the circulant matrix model

Xavier Buffat, Tatiana Pieloni, Adrian Oeftiger

A new model for the description of beam instabilities in synchrotrons featuring wakefields and space charge forces is proposed, using the circulant matrix approach. The predictions of this model are discussed in light of past ones, with a particular emphas ...
