重离子碰撞中的开放重味产生

Open Heavy Flavor Production in Heavy Ion Collisions

J. C. Dunlop

摘要:

近年来,重部分子、魅力和美与重离子碰撞中产生的物质的相互作用引起了人们极大的兴趣。重的部分子被预测与物质的相互作用不如轻的部分子强烈。与这些预测明显相反的是,已经看到了来自重味衰变的非光子电子的出乎意料的强抑制。然而,无论是在测量本身,还是在将魅力和美丽的贡献分开方面,都存在重大的实验不确定性,这使得对这些结果的解释变得复杂。对当前的实验情况进行了严格审查,并讨论了使这些测量更容易解释的前景。

英文摘要:

The interaction of heavy partons, charm and beauty, with the matter created in heavy ion collisions has been of great interest in recent years. Heavy partons were predicted to interact less strongly with the matter than light partons. In apparent contrast to these predictions, unexpectedly strong suppression of non-photonic electrons from heavy flavor decays has been seen. However, significant experimental uncertainties remain, both in the measurements themselves and in the separation of the contribution from charm and beauty, which have complicated the interpretation of these results. The current experimental situation is critically reviewed and prospects for making these measurements more easily interpretable discussed.
