We present three measurements of the top-quark mass in the lepton plus jets channel with approximately 1:9 fb À1 of integrated luminosity collected with the CDF II detector using quantities with minimal dependence on the jet energy scale. One measurement exploits the transverse decay length of b-tagged jets to determine a top-quark mass of 166:9 þ9:5 À8:5 ðstatÞ AE 2:9ðsystÞ GeV=c 2 , and anoth...

The more information a measurement provides about a quantum system's position statistics, the less information a subsequent measurement can provide about the system's momentum statistics. This information trade-off is embodied in the entropic formulation of the uncertainty principle. Traditionally, uncertainly relations correspond to resolution limits; increasing a detector's position sensitivi...

S. Chatrchyan et al.* (CMS Collaboration) (Received 17 August 2011; published 14 November 2011) A new measurement of the inclusive production cross section for pp ! t t is performed at a center-ofmass energy of 7 TeV using data collected by the CMS experiment at the LHC. The analysis uses a data sample corresponding to an integrated luminosity of 36 pb , and is based on the final state with one...

We present the first measurement of the inclusive three-jet differential cross section as a function of the invariant mass of the three jets with the largest transverse momenta in an event in p ¯ p collisions at √ s = 1.96 TeV. The measurement is made in different rapidity regions and for different jet transverse momentum requirements and is based on a data set corresponding to an integrated lu...

CHEST, 79: 4, APRIL, 1981 limitation, Simon3 has suggested using an absolute measurement of the transverse heart diameter, and normative data are available. These data, taken from 100 normal chest radiographs, puts the upper limit of normal at 15.5 cm in the male and 14.00 cm in the female (with median values of 12.5 and 11.5 cm respectively). In the 100 chest radiographs reviewed by Simon and ...

A compact modulated birefringence-measurement system has been developed for use in microgravity fluid physics applications with non-Newtonian fluids such as polymer solutions. This instrument uses a dual-crystal transverse electro-optical modulator capable of modulation frequencies in excess of 100 MHz. The two crystals are modulated 180◦ out of phase from each other. The theoretical framework ...

Bunch lengths as short as 84 fs (rms) have been measured at Jefferson Lab using a zero-phasing RF technique. To the best of our knowledge, this is the first accurate bunch length measurement in this regime. In this letter, an analytical approach for computing the longitudinal distribution function and bunch length is described for . arbitrary longitudinal and transverse distributions. The measu...

We determine the optimal laser and e + /e − energies and polarizations for directly determining the CP eigenvalue of each of the neutral Higgs bosons of the Minimal Supersymmetric Model via measurement of transverse polarization cross section asymmetry in back-scattered laser photon collisions. Approximate statistical sig-nificances are computed for the measurement of the CP eigenvalue as a fun...

A new method for the measurement of tibial torsion using computerised transverse tomography is presented. Its accuracy is equal to that of cadaveric skeletal measurement. This method may be used in patients with unilateral post-traumatic torsional deformities, especially when these are combined with genu varum or valgum. The study of torsional aberrations in connection with congenital abnormali...

This paper introduces an optical AC voltage sensor based on the transverse Pockels effect. The sensor utilizes a bulk Bi(4)Ge(3)O(12) (BGO) crystal as the sensing element. The measurement principle has been described and prototype of the sensor has been constructed and evaluated. Good linearity and accuracy performance was obtained for AC voltage measurement. The proposed sensor can be thus app...
