Zeptosecond dynamics in atoms: fact or fiction?

T. Nandi, Prashant Sharma, Soumya Chatterjee +5

Photon exchange due to nuclear bremsstrahlung during nuclear collisions can cause Coulomb excitation in the projectile and the target nuclei. The corresponding process originated i…

Search for light sterile neutrinos with the T2K far detector Super-Kamiokande at a baseline of 295 km

K. Abe, R. Akutsu, A. Ali +318

We perform a search for light sterile neutrinos using the data from the T2K far detector at a baseline of 295 km, with an exposure of 14.7 (7.6) protons on target i…

Search for CP violation in Neutrino and Antineutrino Oscillations by the T2K experiment with protons on target

K. Abe, R. Akutsu, A. Ali +319

The T2K experiment measures muon neutrino disappearance and electron neutrino appearance in accelerator-produced neutrino and antineutrino beams. With an exposure of $14.7(7.6)\tim…

Measurement of the charged-current cross sections on water, hydrocarbon, iron, and their ratios with the T2K on-axis detectors

K. Abe, R. Akutsu, A. Ali +314

We report a measurement of the flux-integrated charged-current cross sections on water, hydrocarbon, and iron in the T2K on-axis neutrino beam with a mean neutrino energy o…

New Window Resonances in the Potassium 3s Photoabsorption Spectrum

M. Koide, F. Koike, R. Wehlitz +7

The photoion spectrum of atomic potassium was measured over the 3s -> np excitation region with the photoion time-of-flight method and monochromatized synchrotron radiation. An unu…

Search for heavy neutrinos with the T2K near detector ND280

K. Abe, R. Akutsu, A. Ali +325

This paper reports on the search for heavy neutrinos with masses in the range MeV/c using the off-axis near detector ND280 of the T2K experiment. These partic…

An accurate determination of the Avogadro constant by counting the atoms in a 28Si crystal

B. Andreas, Y. Azuma, G. Bartl +23

The Avogadro constant links the atomic and the macroscopic properties of matter. Since the molar Planck constant is well known via the measurement of the Rydberg constant, it is al…

Expected Performance of the ATLAS Experiment - Detector, Trigger and Physics

The ATLAS Collaboration, G. Aad, E. Abat +2604

A detailed study is presented of the expected performance of the ATLAS detector. The reconstruction of tracks, leptons, photons, missing energy and jets is investigated, together w…

Zeptosecond to attosecond dynamics in atoms and possibility of generating a zeptosecond light source

T. Nandi, Soumya Chatterjee, Adya P. Mishra +3

In nuclear collisions, nuclear bremsstrahlung can cause nuclear Coulomb excitation via photon exchange in the projectile as well as the target nuclei. Such a process originating in…

Search for neutral-current induced single photon production at the ND280 near detector in T2K

K. Abe, R. Akutsu, A. Ali +314

Neutrino neutral-current induced single photon production is a sub-leading order process for accelerator-based neutrino beam experiments including T2K. It is, however, an important…
