ILC Reference Design Report Volume 3 - Accelerator

R. Erbacher, T. Mimashi, Jin‐Young Jung, Hai-Tao Wang et autres

The International Linear Collider (ILC) is a 200-500 GeV center-of-mass high-luminosity linear electron-positron collider, based on 1.3 GHz superconducting radio-frequency (SCRF) accelerating cavities. The ILC has a total footprint of about 31 km and is designed for a peak luminosity of 2x10^34 …

The discovery of the b quark at Fermilab in 1977: The experiment coordinator’s story

J. K. Yoh

I present the history of the discovery of the Upsilon (Υ) particle (the first member of the b-quark family to be observed) at Fermilab in 1977 by the CFS (Columbia-Fermilab-Stony Brook collaboration) E288 experiment headed by Leon Lederman. We found the first …

10th Topical Workshop on Proton-Antiproton Collider Physics, Batavia, IL May 1995

R. Raja, J. K. Yoh

This book represents recent findings in high energy physics, specifically the discovery of the long sought after top quark. It also highlights the large number of b-physics results coming from the hadron colliders, comparative to the results of the electron colliders. It …

Observation of P -Wave bb¯ Bound States

K. Han, T. Böhringer, P. Franzini, G Mageras et autres

The existence of $P$-wave $b\overline{b}$ bound states ${{\ensuremath{\chi}}_{b}}^{\ensuremath{'}}$ is demonstrated by observation of photons from the transition ${\ensuremath{\Upsilon}}^{\ensuremath{'}\ensuremath{'}}\ensuremath{\rightarrow}\ensuremath{\gamma}+{{\ensuremath{\chi}}_{b}}^{\ensuremath{'}}$ in the inclusive photon spectrum from ${\ensuremath{\Upsilon}}^{\ensuremath{'}\ensuremath{'}}$ decays. The center of gravity of the observed photon energies is 98 MeV and the branching ratio …

Evidence for χb′ Production in the Exclusive Reaction ϒ′′→γχb′→(γγϒ′ or γγϒ)

G. Eigen, G. Blanar, H. Dietl, E. Lorenz et autres

Evidence is presented for the production of ${{\ensuremath{\chi}}_{b}}^{\ensuremath{'}}$ states ($2^{3}P$) in the reaction ${\ensuremath{\Upsilon}}^{\ensuremath{'}\ensuremath{'}}\ensuremath{\rightarrow}\ensuremath{\gamma}{{\ensuremath{\chi}}_{b}}^{\ensuremath{'}}\ensuremath{\rightarrow}\ensuremath{\gamma}\ensuremath{\gamma}{\ensuremath{\Upsilon}}^{\ensuremath{'}} (or \ensuremath{\gamma}\ensuremath{\gamma}\ensuremath{\Upsilon})$ with subsequent decay of the ${\ensuremath{\Upsilon}}^{\ensuremath{'}}(\ensuremath{\Upsilon})$ into ${e}^{+}{e}^{\ensuremath{-}}$ or ${\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}$. The data were obtained with the nonmagnetic CUSB detector at the Cornell ${e}^{+}{e}^{\ensuremath{-}}$ storage ring. Observed …
