通过电荷半径测量约束BER 47的低能质子俘获

Constraining Low-Energy Proton Capture on Beryllium-7 through Charge Radius Measurements

Emil Ryberg, Christian Forssén, H. -W. Hammer, Lucas Platter

摘要:

在本文中,我们指出,硼-8的电荷半径的测量提供了间接访问的S-因子的辐射质子捕获在BER 17 -7在低能量。我们用头阶晕有效场论来探讨这种关联,并给出了电荷半径与S因子之间的关系。此外,我们提出了重要的技术方面的重整化的点状P波相互作用中存在的排斥库仑相互作用。

英文摘要:

In this paper, we point out that a measurement of the charge radius of Boron-8 provides indirect access to the S-factor for radiative proton capture on Beryllium-7 at low energies. We use leading-order halo effective field theory to explore this correlation and we give a relation between the charge radius and the S-factor. Furthermore, we present important technical aspects relevant to the renormalization of pointlike P-wave interactions in the presence of a repulsive Coulomb interaction.
