Area of Science:

• High-energy nuclear physics
• Quantum Chromodynamics (QCD)
• Particle physics

Background:

• Heavy quark production, specifically open charm and bottom, provides insights into the strong interaction dynamics governed by Quantum Chromodynamics (QCD).
• Relativistic heavy ion collisions (RHIC) offer a unique environment to study these phenomena under extreme conditions.
• Understanding nuclear effects is crucial for interpreting experimental data from heavy ion collisions.

Purpose of the Study:

• To provide up-to-date Quantum Chromodynamics (QCD) predictions for open charm and bottom production at RHIC.
• To calculate the electron spectrum from heavy flavor decays for direct experimental comparison.
• To establish a rigorous theoretical benchmark, including uncertainties, for identifying nuclear effects.

Main Methods:

• Utilizing advanced Quantum Chromodynamics (QCD) calculations for heavy quark production.
• Simulating heavy flavor decays to predict the resulting electron spectrum.
• Quantifying theoretical uncertainties inherent in the predictions.

Main Results:

• Presented state-of-the-art QCD predictions for open charm and bottom production cross-sections at RHIC.
• Calculated the electron momentum spectrum originating from the decay of heavy quarks.
• Established a comprehensive theoretical baseline for comparison with experimental data.

Conclusions:

• The provided theoretical predictions serve as a critical benchmark for experimental searches for nuclear effects.
• Direct comparison of calculated electron spectra with RHIC data can reveal modifications to heavy quark production in nuclear matter.
• This work facilitates the interpretation of experimental results and advances the understanding of QCD in nuclear environments.
