Thermal blurring of event-by-event fluctuations generated by rapidity conversion
Thermal blurring of event-by-event fluctuations generated by rapidity conversion
We study the effect of thermal blurring caused by the use of (momentum-space) rapidity as a proxy of coordinate-space rapidity in experimental measurements of conserved-charge fluctuations in relativistic heavy-ion collisions. In theoretical studies assuming statistical mechanics, calculated fluctuations are those in a spatial volume. Experiments, on the other hand, can …
