Size distributions of NLC particles as determined from 3-color observations of NLC by ground-based lidar

CSIR-NLC Mobile LIDAR - First Scientific Result

In this paper, we present the obtained first scientific results from CSIR-NLC mobile LIDAR (LIght Detection And Ranging) and its validation/comparison with other ground and space-borne measurements. The LIDAR results are compared using aerosol measurements from the Stratosphere Aerosol Gas Experiment (SAGE) and Optical depth derived from sun-photometer employed under AErosol RObotic NETwork (AE...

Nlc ∗

We demonstrate that the process e + e − → tth at the NLC provides a powerful tool for extracting the tt (Yukawa) couplings of the h. In combination with the e + e − → Zh process , an accurate determination of the ZZ coupling of the h is also possible. The resulting ability to distinguish different models of the Higgs sector is illustrated by detailed studies for two-Higgs-doublet models. In ext...

Impact of Final-Focus Ground Motion on NLC Luminosity*

Vertical displacements of final-focus quadrupoles due to ground motion can cause the two beams of the Next Linear Collider (NLC) to miss each other at the interaction point (IP) and in addition, will increase the IP spot size, and thus degrade the luminosity, by generating dispersion and skew coupling. The sensitivity of the final-focus optics to plane ground waves is strongly wavelength depend...

Simulation Studies of the NLC with Improved Ground Motion Models

The performance of various systems of the Next Linear Collider (NLC) have been studied in terms of ground motion using recently developed models. In particular, the performance of the beam delivery system is discussed. Plans to evaluate the operation of the main linac beam-based alignment and feedback systems are also outlined.
