Maximizing Particle Detection at the LHC: The Role of Photons, Jets, and Leptons

In summary, the conversation discusses the preference for detecting particles at the LHC using final states of photons. The speaker explains that while photons have better energy resolution, they are less frequent than jets in most processes. The mention of leptons is also brought up, with the suggestion that they may have advantages over photons in terms of detection.

Hi all,

Is it not preferable to detect a particle at the LHC with final states of photons, that when I read
in many papers I find for example for a particle beyond SM like an octet scalars if they could decay
into jets and photons+jets ( S^+ -> S^- A -> t b A), only jets channels take a concern, so do jets or
leptons detection has advantages than photons siganls ?

Bests,
Safinaz

Where are the photons in your process?
And if you just look at the different channels, are there different numbers of photons?

Photons are nice (better energy resolution as for jets), but for most processes they are less frequent than jets.
Leptons are even better - you can track their path and get a good position and momentum resolution. And muons are easy to identify.

1. How are photons detected at the LHC?

Photons are detected at the LHC using specialized detectors called "calorimeters." These detectors are made of layers of dense material that cause the photons to interact and deposit their energy, creating a signal that can be measured.

2. What is the purpose of detecting photons at the LHC?

Detecting photons at the LHC allows scientists to study the properties of particles produced in high-energy collisions. Photons can provide insight into the composition and behavior of these particles, helping us to better understand the fundamental forces and particles that make up our universe.

3. How are the photons produced at the LHC?

Photons are produced at the LHC through collisions between high-energy particles, such as protons or lead ions. These collisions release an enormous amount of energy, which can be converted into photons. The LHC is able to produce a large number of high-energy collisions, making it an ideal environment for studying photons.

4. What are some challenges in detecting photons at the LHC?

One challenge in detecting photons at the LHC is the high amount of background noise from other particles and radiation. This noise can make it difficult to distinguish between the signals from photons and other particles. Additionally, photons are neutral particles, meaning they do not leave a trace in the magnetic fields used to track charged particles.

5. How do scientists analyze the data from detecting photons at the LHC?

The data from detecting photons at the LHC is analyzed using complex algorithms and statistical techniques. Scientists look for patterns and trends in the data to identify signals from photons and filter out noise. This data analysis is crucial in making discoveries and furthering our understanding of the fundamental building blocks of the universe.
