Measurement of the Open Charm Cross-Section in $\sqrt{s_{NN}}$ = 200 GeV Cu+Cu Collisions at STAR

TL;DR

This paper reports the measurement of open charm production cross-section in Cu+Cu collisions at 200 GeV using direct reconstruction of D mesons, providing data for understanding charm quark behavior in heavy-ion collisions.

Contribution

It presents the first direct reconstruction-based measurement of open charm cross-section in Cu+Cu collisions at RHIC, comparing results with theoretical models and previous experiments.

Findings

Charm cross-section measured and reported.

Results compared with theoretical predictions.

Data consistent with prior RHIC measurements.

Abstract

We present the mid-rapidity $(D^{0} + \bar{D^{0}})/2$ yield measured in $\sqrt{s_{NN}}$ = 200 GeV Cu+Cu collisions at RHIC via direct reconstruction through the $K\pi$ decay channel. A charm cross-section is reported and compared to theoretical predictions and to previous RHIC experimental results.
