Response to the He interpretation of MAMI's recent determination of H)

Ryoko Kino, Patrick Achenbach, Pascal Klag +5

We respond to the recent suggestion by A. Gal [arXiv:2604.18259] that the sharp pion-momentum peak at ~MeV/ observed in our $^7\mathrm{Li}(e,e^\prime K^+)…

Compact sub-10 ps Resolution Radio Frequency Photomultiplier Tube

Sergey Abrahamyan, Simon Zhamkochyan, Hasmik Rostomyan +16

Experimental measurements of the radial spreading of photoelectrons emitted from a multi-alkali photocathode in a MCP-based photomultiplier tube have shown that, for photon wavelen…

A Helical-Deflector-Based Radio-Frequency Spiral Scanning System for keV Energy Electrons

Simon Zhamkochyan, Vanik Kakoyan, Vardan Bardakhchyan +21

We present the design, modeling, and experimental validation of a radio-frequency based time-to-position conversion system for keV electrons incorporating a helical deflector opera…

Precise measurement of the -binding energy difference between H and H via decay-pion spectroscopy at MAMI

Ryoko Kino, Sho Nagao, Patrick Achenbach +31

We performed high-precision decay-pion spectroscopy of light hypernuclei at the Mainz Microtron (MAMI) using the A1 spectrometer facility. By measuring the monochromatic …

Dihadron Transverse-Spin Asymmetries in Muon-Deuteron Deep-Inelastic Scattering

G. D. Alexeev, M. G. Alexeev, C. Alice +168

In 2022, the COMPASS collaboration performed semi-inclusive measurements of deep-inelastic muon-scattering on a transversely polarised deuteron (6LiD) target. From these data, tran…
