Detection of Black Holes

Detection of Black Holes

Although black holes were theoretically postulated in the 1920s, they remained outside the domain of observational astronomy until the 1970s.
Their closest cousins are neutron stars, which are composed almost entirely of neutrons packed against each other, making them extremely dense. A neutron star has the same mass as the Sun but its diameter is only a few kilometers. Therefore, the escape velocity from their surface is close to the speed of light.
Not until the 1960s, when the first neutron...

Area of Science:

High-energy particle physics
Collider physics
Experimental particle physics

Background:

The Large Hadron Collider (LHC) is currently the world's most powerful particle accelerator.
Future upgrades are necessary to maintain its leading role in scientific discovery.
The High-Luminosity LHC (HL-LHC) program aims to significantly enhance the LHC's capabilities.

Purpose of the Study:

To provide an overview of the High-Luminosity LHC (HL-LHC) program.
To outline the scientific potential and technological challenges of the HL-LHC.
To detail the necessary upgrades for the accelerator and its detectors (ATLAS and CMS).

Main Methods:

The HL-LHC program requires upgrades to the injector system, accelerator complex, and luminosity levelling.
Experiments ATLAS and CMS need substantial system upgrades to handle increased interaction rates and radiation.
Key upgrades include new tracking systems, advanced calorimeter endcaps, and picosecond precision timing detectors.

Main Results:

The HL-LHC will deliver an order of magnitude greater integrated luminosity at 14 TeV.
Detector upgrades will enable experiments to cope with higher interaction rates and radiation levels.
New technologies, such as tilted pixel modules and advanced outer trackers, are being implemented.

Conclusions:

The HL-LHC program will significantly enhance the physics performance of the ATLAS and CMS experiments.
It will address computing challenges posed by large datasets.
The program will focus on precision measurements of the Standard Model, Higgs boson characterization, and searches for new physics beyond the Standard Model.
