Proposal; Precise measurements of very forward particle production at RHIC

TL;DR

This paper proposes a new experiment at RHIC to precisely measure very forward particle production using a high-resolution calorimeter setup, aiming to improve understanding of particle spectra at extreme pseudorapidities.

Contribution

It introduces a novel experimental setup at RHIC, adapting the LHCf Arm2 detector for forward particle measurements at high pseudorapidity.

Findings

Design of the RHICf experiment and detector placement

Expected high-precision measurements of photon, neutron, and pi0 spectra

Potential to enhance understanding of forward particle production

Abstract

We propose a new experiment Relativistic Heavy Ion Collider forward (RHICf) for the precise measurements of very forward particle production at RHIC. The proposal is to install the LHCf Arm2 detector in the North side of the ZDC installation slot at the PHENIX interaction point. By installing high-resolution electromagnetic calorimeters at this location we can measure the spectra of photons, neutrons and pi0 at pseudorapidity eta>6.
