The ILD Detector: A Versatile Detector for an Electron-Positron Collider at Energies up to 1 TeV

H. Abramowicz, D. Ahmadi, J. Alcaraz +276

The International Large Detector, ILD, is a detector concept for an experiment at a future high energy lepton collider. The detector has been optimised for precision physics in a r…

Improved measurements of neutron lifetime with cold neutron beam at J-PARC

Y. Fuwa, T. Hasegawa, K. Hirota +28

The ``neutron lifetime puzzle'' arises from the discrepancy between neutron lifetime measurements obtained using the beam method, which measures decay products, and the bottle meth…

Performance of the Fully-equipped Spin Flip Chopper For Neutron Lifetime Experiment at J-PARC

K. Mishima, G. Ichikawa, Y. Fuwa +19

To solve the ''neutron lifetime puzzle,'' where measured neutron lifetimes differ depending on the measurement methods, an experiment with pulsed neutron beam at J-PARC is in progr…

Precise Neutron Lifetime Measurement Using Pulsed Neutron Beams at J-PARC

N. Sumi, K. Hirota, G. Ichikawa +18

A neutron decays into a proton, an electron, and an anti-neutrino through the beta-decay process. The decay lifetime (880 s) is an important parameter in the weak interaction…

Neutron lifetime measurement with pulsed cold neutrons

K. Hirota, G. Ichikawa, S. Ieki +26

The neutron lifetime has been measured by comparing the decay rate with the reaction rate of He nuclei of a pulsed neutron beam from the spallation neutron source at the Japan…

Optimization study of scintillator shape of electromagnetic calorimeter for Higgs factories

Takanori Mogi, Tomohiko Tanabe, Wataru Ootani +5

Scintillator-based calorimeters for experiments at Higgs factories (e.g. ILC) demand scintillator designs that can detect sufficient number of photons and have good light yield uni…
