[Alert_collaboration] [External] Abstract for APS/GHP 2023

[Meziani, Zein-Eddine]

Hello Mikhail,

The abstract reads well except for small suggestions I have. I highlighted them in red and gave suggestions below the text.

I hope this helps.

Zein-Eddine


A series of experiments were proposed to study the fundamental structure of light nuclei, such as 2H and 4He. The program focuses on the ex- ploration of the nuclear Generalized Parton Distributions (GPDs), EMC effects, as well as the nature and origin of nuclear effects. The key feature of these measurements is the challenging detection of the low-momentum recoil particles in a large kinematic range (xx<Q^2<xx, xx<x<xx ). For this purpose, A Low Energy Recoil Tracker (ALERT) is being built to work in conjunction with the CLAS12 spectrometer to measure recoil fragments with momenta as low as xxx MeV/c. The ALERT detector consists of a low gain stereo drift chamber and a scintillator array allowing reliable separation of 4He, 3He, 3H, deuterons, and protons. Implementation of new artificial intelligence (AI) track reconstruction methods are proven to be beneficial for experiments conducted at high instantaneous luminosities in which the number of background hits is significantly increased. The improved tracking accu- racy and overall particle identification that can be achieved with modern machine-learning techniques are crucial for these experiments. In this talk, a brief highlight of the ALERT program will be given along with the status of the AI-assisted tracking under development.

1- "Large kinematic range" with respect compared to what? You emphasized low momenta < 100 MeV/c.  Perhaps it is worth being more specific with values of Q^2 and x for the photon and then mention recoil momenta as low 50 MeV or whatever limit you think is achievable. The proposal mentions "as low as possible" for the momentum of the recoiling 3H, 3He, D, p.

2- "are proven" or “proved" to be beneficial

3-"under-development” listed before AI-assisted tracking could be confusing to the reader. I suggest putting it
