CMS Trigger: Lessons from LHC Run 2

by Alex Tapper (Imperial College London)

RPC Trigger CrateThe CMS trigger outperformed during Run 2, efficiently recording data for the CMS versatile physics programme

The CMS beam pipe will be replaced in LS2, with one that will allow the extremities of the future pixel detectors to get even closer to the interaction point. 

CMS upgrade plans for LS2

by Panos Charitos

In order to achieve the full benefit of the HL-LHC, CMS has launched an intensive R&D programme along with major work on key infrastructures during LS2.

HL-LHC computational challenge for ATLAS and CMS experiments

by Tommaso Boccali (INFN and CERN) Davide Costanzo (Sheffield U and CERN)

Discussing the computing models and future resource needs for ATLAS and CMS experiments and the possibilities opened up by quantum computing.

Higgs boson observed decaying to bottom quarks

by Panagiotis Charitos

Last month, the ATLAS and CMS collaborations jointly announced the discovery of the Higgs boson decaying into a matter-antimatter pair of bottom quarks.

Developing new electronics for the CMS tracking system

by Panos Charitos. Kostas Kloukinas

An ongoing R&D programme aims to tackle the challenges of tracking and identifying new particles with the CMS detector in the challenging environment of HL-LHC. 

Axion-like particle searches at the LHC

by Andrea Thamm, Tom Melia, Panos Charitos

An overview of LHC searches for Axion-like particles (ALPs) both at proton-proton and heavy-ion collisions. 

Mapping the CMS inner tracking system with unprecedented precision

by Phil Baringer, Maxime Gouzevitch and Anna Kropivnitskaya

The CMS Collaboration’s 800th paper describes a technique for measuring the positions of inactive elements using Nuclear Interactions.

Precise timing detectors for the LHC experiments

by Panos Charitos, with contributions from Tommaso Tabarelli de Fatis (CMS), Lindsey Gray (CMS), Ana Maria Henriques Correia (ATLAS) and Laurent Serin (ATLAS)

 To meet the physics goals of the HL-LHC physics programme, ATLAS and CMS experiments have submitted proposals for timing detectors that will boost their physics reach.
