New Extended Method for Ψ′ Scaling Function of Inclusive Electron Scattering

Cited 3|Views26

Abstract

Scaling analyses have been successfully applied to study the inclusive electron scattering ( e, e′ ) over the past few decades. In this study, we utilize the ψ′ scaling function in momentum space to analyze the ( e, e′ ) cross sections, where the nucleon momentum distributions are derived from self-consistent mean-field calculations. By further introducing the energy and momentum conservation in the scaling analysis, an improved ψ′ scaling function is proposed to investigate the high-momentum part of the momentum distributions. Using the proposed scaling function, we systematically explore the effects of the nucleon-nucleon short-range correlation ( NN -SRC) on the ( e, e′ ) cross sections. From the experimental ( e, e′ ) data, the NN -SRC strength is further extracted within the framework of the improved ψ′ scaling function. The studies in this paper offer a new method to investigate the nucleon momentum distributions and the NN -SRC effects in nuclei.

Pretraining has recently greatly promoted the development of natural language processing (NLP)
We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
