Continuum limits of Berenstein–Maldacena–Nastase matrix theory: where is the (non-Abelian) gauge group?
Abstract We discuss the continuum limits of Berenstein–Maldacena–Nastase matrix model. The special attention is paid to limits that give rise to Poisson bracket gauge field theories with gauge groups U(n) on the ordinary two sphere. The gauge group...

Complete two loop electroweak contributions to the muon lifetime in the Standard Model
Abstract An independent result for the two loop fermionic contributions to the muon lifetime in the Standard Model is obtained and slight deviations in the prediction of the W boson mass are found with respect to [Phys. Lett. B 495 (2000) 338; Nucl. ...

Infrared regularization of baryon chiral perturbation theory reformulated
Abstract We formulate the infrared regularization of Becher and Leutwyler in a form analogous to our recently proposed extended on-mass-shell renormalization. In our formulation, IR regularization can be applied to multi-loop diagrams with an...

Hard photodisintegration of a proton pair in 3He
Abstract Hard photodisintegration of the deuteron has been extensively studied in order to understand the dynamics of the transition from hadronic to quark–gluon descriptions of the strong interaction. In this Letter, we discuss the extension of...

Electromagnetic form factor of the pion in the space- and time-like regions within the front-form dynamics
Abstract The pion electromagnetic form factor is calculated in the space- and time-like regions from −10 (GeV/c)2 up to 10 (GeV/c)2, within a front-form model. The dressed photon vertex where a photon decays in a quark–antiquark pair is depicted...

Enhancement of charm quark production due to nonlinear corrections to the DGLAP equations
Abstract We have studied how parton distributions based on the inclusion of nonlinear scale evolution and constraints from HERA data affect charm production in pp collisions at center-of-mass energies of 5.5, 8.8 and 14 TeV. We find that, while the...

Analysis of Muon Events in the DHCAL
Abstract The Digital Hadron Calorimeter (DHCAL) is a large prototype of an imaging calorimeter using Resistive Plate Chambers (RPCs) as active media. The readout is segmented into 1×1cm2 pads, each with a single bit resolution, hence the...

Calibration and Performance of the Precision Chambers of the ATLAS Muon Spectrometer
Abstract The ATLAS muon spectrometer consists of a system of precision tracking and trigger chambers embedded in a 2T magnetic field generated by three large aircore superconducting toroids. The precision Monitored Drift Tube (MDT) chambers measure...

Improved Poynting's Vector Method: AC Loss Measurement of HTS Tapes Formed into a Short Straight or a Solenoidal Coil
Abstract Improved Poynting's vector method without movements was proposed to measure ac losses of HTS tapes, formed into a short straight or a solenoidal coil, which were carrying ac transport currents under transverse ac magnetic fields. In the...

Display of probability densities for data from a continuous distribution
Abstract Based on cumulative distribution functions, Fourier series expansion and Kolmogorov tests, we present a simple method to display probability densities for data drawn from a continuous distribution. It is often more e_cient thanusing...

A webcam in Bayer-mode as a light beam profiler for the near infra-red
Abstract Beam profiles are commonly measured with complementary metal oxide semiconductors (CMOS) or charge coupled devices (CCD). The devices are fast and reliable but expensive. By making use of the fact that the Bayer-filter in commercial webcams ...

Rashba and Dresselhaus spin-orbit interaction strength in GaAs/GaAlAs heterojunctions
Abstract Using a recently developed variational theory for the spin split subbands, we investigate the relative strength of the Rashba and Dresselhaus spin orbit terms in GaAs/GaAlAs heterojunctions. The envelope function formalism is employed using ...

Higgs production via gluon–gluon fusion with finite top mass beyond next-to-leading order
Abstract We present a computation of the cross section for inclusive Higgs production in gluon–gluon fusion for finite values of the top mass in perturbative QCD to all orders in the limit of high partonic center-of-mass energy. We show that at NLO...
