<div dir="ltr">Dear Colleagues,<br><br>I'd like to bring your attention to our latest research on the proton charge radius that has been published today in Physical Review D (see <a href="https://urldefense.proofpoint.com/v2/url?u=https-3A__doi.org_10.1103_PhysRevD.105.054004&d=DwMFaQ&c=CJqEzB1piLOyyvZjb8YUQw&r=V3XNY-MaMKN2LuAaTdObrA&m=dfX8coqshXUbElaF_oWnz2EbQ4pNx-8RkX-tik-kc9NtcV2sQ9B2IF9LucQwSwqB&s=LK4nhe9UhLDNXS2iQ5dRecwP6GHu1fsdDtPyp2vdLzU&e=">https://doi.org/10.1103/PhysRevD.105.054004</a>). This result may be of some interest for the PRad-II experiment and analysis. Note that there are several new appendices compared to the preprint version posted on arXiv a year ago (<a href="https://urldefense.proofpoint.com/v2/url?u=https-3A__arxiv.org_abs_2102.13022&d=DwMFaQ&c=CJqEzB1piLOyyvZjb8YUQw&r=V3XNY-MaMKN2LuAaTdObrA&m=dfX8coqshXUbElaF_oWnz2EbQ4pNx-8RkX-tik-kc9NtcV2sQ9B2IF9LucQwSwqB&s=KZAfbfScAj9q5XWgFjWrYvNK7bH-U63zfwpCZ5hiaug&e=">https://arxiv.org/abs/2102.13022</a>). Please don't hesitate to contact me if you have any questions or comments.<br><br>Best regards,<br><div>Alexander Gramolin</div><div><br></div></div>
