Measurement of the W + W - Threshold

چکیده
Scan strategies for the measurement of--the e+e+ W+W-. threshold arg discussed. The most sensitive beam energies (I&) for the measurement of the T/lr mass (.k!w) and width (I?w are Eb N ik!tv + 0.5 GeV and Eb N &lw 1 GeV, ) respectively. With a commitment of 250 pb-’ to the measurement of the W-pa.ir threshold, it appears to be possible measure Mw with a precision SMw 2 160 MeV. The corresponding precision on the width, 0’w = 400-500 MeV, is not competitive with recent indirect determinations from the CDF and UA2 collaborations.

The measurement of solar ultraviolet radiation in Kermanshah city over a one-year period from 2015 to 2016
ABSTRACT Background: Ultraviolet radiation is present in sunlight. If ultraviolet radiation exceeds the limit, it can cause detrimental effects on human health such as skin cancer and cataract. Materials and Methods: In this descriptive cross-sectional study, the level of solar ultraviolet radiation type A (UVA) were measured using UV LOG HAND HELD in Kermanshah city. The intensity of ultravio...
متن کاملPolyamide Forward Osmosis Membrane: Synthesis, Characterization and Its Performance for Humic Acid Removal
In this research, modification on the ultrafiltration (UF) membrane by synthesis of a thin layer of polyamide selective layer was designed for high performances of forward osmosis (FO) water treatment. Two monomers, m-Phenylenediamine (MPD) and Trimesoyl chloride (TMC) with different concentrations of MPD (2.0% w/v and 1.0% w/v) were reacted with TMC (0.15% w/v) for interfacial polymerization (...

In the present paper, the influence of cobalt additive on the sintering/infiltration behavior of W-Cu composite was studied. For this purpose, the mixed powders of tungsten and cobalt were compacted by CIP method and then sintered at 1450, 1550 and 1600 °C in a hydrogen atmosphere. The sintered specimens at 1550 °C were subsequently infiltrated with liquid copper at 1250 °C for 10, 60 and 1...
متن کاملON THE STABILITY AND THRESHOLD ANALYSIS OF AN EPIDEMIC MODEL
We consider a mathematical model of epidemic spread in which the population is partitioned into five compartments of susceptible S(t), Infected I(t), Removed R(t), Prevented U(t) and the Controlled W(t). We assume each of the compartments comprises of cohorts of individuals which are identical with respect to the disease status. We derive five systems of equations to represent each of the ...
