Abstract

Physics prospects for High-Luminosity LHC with the ATLAS detector are presented. The results presented here are based on updated and compiled projections published during 2019 in a Yellow Report. They include projections for Standard Model physics, Higgs physics, Beyond Standard Model physics, Flavor physics and QCD matter at high density. These proceedings give some highlights of the ATLAS physics potential in those areas.

Highlights

  • The High-Luminosity LHC (HL-LHC) [1] is expected to start operation in 2026

  • The ATLAS detector [2] will undergo a number of upgrades to cope with the HL-LHC running environment

  • The calorimeters will be upgraded with higher granularity and faster electronics

Summary

Introduction

The High-Luminosity LHC (HL-LHC) [1] is expected to start operation in 2026 (see Fig. 1) It will achieve an instantaneous luminosity of 7.5 × 1034 cm−2s−1 and will collect an integrated luminosity of 3000 fb−1. The ATLAS detector [2] will undergo a number of upgrades to cope with the HL-LHC running environment. 2 (Higgs) [7], Working Group 3 (Beyond the Standard Model) [8], Working Group 4 (Flavor) [9] and Working Group 5 (QCD matter at high density) [10]. These proceedings include some highlights from the 3 first reports
