| Title | Modified Structure of Protons and Neutrons in Correlated Pairs | ||||
| Abstract | The atomic nucleus is made of protons and neu- trons (nucleons), that are themselves composed of quarks and gluons. Understanding how the quark-gluon structure of a nucleon bound in an atomic nucleus is modified by the surrounding nu- cleons is an outstanding challenge. Although ev- idence for such modification, known as the EMC effect, was first observed over 35 years ago, there is still no generally accepted explanation of its cause [1?3]. Recent observations suggest that the EMC effect is related to close-proximity Short Range Correlated (SRC) nucleon pairs in nu- clei [4, 5]. Here we report the first simultane- ous, high-precision, measurements of the EMC effect and SRC abundances. We show that the EMC data can be explained by a universal mod- ification of the structure of nucleons in neutron- proton (np) SRC pairs and present the first data- driven extraction of this universal modification function.
