A Linear Collider Vision for the Future of Particle Physics
H. Abramowicz, E. Adli, F. Alharthi +446
In this paper we review the physics opportunities at linear colliders with a special focus on high centre-of-mass energies and beam polarisation, take a fresh look at the…

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…
