TL;DR
The STAR experiment's dilepton program aims to probe the evolution of strongly-interacting matter using upgraded detectors to measure dielectron and dimuon production across various collision energies.
Contribution
This paper presents preliminary dielectron results from STAR's upgraded detector system and discusses future improvements for dilepton measurements in heavy-ion collisions.
Findings
Preliminary dielectron spectra obtained for Au+Au collisions at multiple energies.
Comparison of experimental results with recent theoretical model calculations.
Plans for future detector upgrades to enhance dilepton measurement capabilities.
Abstract
Dileptons provide ideal penetrating probes of the evolution of strongly-interacting matter. With the Time-of-Flight upgrade, STAR is in a unique position to provide large-acceptance dielectron measurements. We discuss preliminary dielectron results for Au+Au collisions at =19.6 - 200 GeV, and compare to recent model calculations. With upcoming detector upgrades STAR will further improve its dielectron measurements as well as include dimuon measurements.
