Examining student growth in laboratory notebook practices in introductory physics courses

Michael Zwartz, J. Kozminski

Laboratory notebooks serve as the primary records for research experiments, demonstrate how researchers went about their work, and tabulate the data collected in the experiment.Recent undergraduate laboratory recommendations emphasize the importance of helping students develop their scientific documentations skills throughout the curriculum.Learning …

Particle Detection

J. Kozminski

Radioactivity is the spontaneous emission of ionizing radiation or particles from the decay or de-excitation of unstable nuclei. Typically, these nuclear processes occur on energy scales of millions of electron volts. While the term radioactivity often has negative connotations, humans are constantly …

MUON COLLIDER DETECTOR BACKGROUNDS

M.A.C. Cummings, S. Kahn, D. Hedin, J. Kozminski

Technological innovations in recent years have revived interest in muon colliders as the next generation energy frontier machine. Advances in muon cooling technology will make the focussing and acceleration of muons to TeV energies possible. The biggest challenge for muon colliders is …

Physics Validation of Monte Carlo Simulations for Detector Backgrounds at a Muon Collider

Erratum to: “Search for particles decaying into a Z boson and a photon in pp¯ collisions at s=1.96 TeV ” [Phys. Lett. B 641 (2006) 415]

V. M. Abazov, B. Abbott, M. Abolins, B. S. Acharya et autres

We present the results of the first search for a new particle X produced in $p\bar{p}$ collisions at \sqrt{s}=1.96 TeV and subsequently decaying to Z\gamma. The search uses 0.3 fb$^{-1}$ of data collected with the D{\O}detector at the Fermilab Tevatron Collider. We …

Erratum: Measurement of σ(pp¯→Z)·Br(Z→ττ) at s=1.96 TeV [Phys. Rev. D71, 072004 (2005)]

V. M. Abazov, B. Abbott, M. Abolins, B. S. Acharya et autres

We present a measurement of the cross section for $Z$ production times the branching fraction to $\tau$ leptons, $\sigma \cdot$Br$(Z\to \tau^+ \tau^-)$, in $p \bar p$ collisions at $\sqrt{s}=$1.96 TeV in the channel in which one $\tau$ decays into $\mu \nu_{\mu} \nu_{\tau}$, …

Multivariate searches for single top quark production with the D0 detector

V. M. Abazov, B. Abbott, M. Abolins, B. S. Acharya et autres

We present a search for electroweak production of single top quarks in the $s$-channel ($p\overline{p}\ensuremath{\rightarrow}t\overline{b}+X$) and $t$-channel ($p\overline{p}\ensuremath{\rightarrow}tq\overline{b}+X$) modes. We have analyzed $230\text{ }\text{ }{\mathrm{pb}}^{\ensuremath{-}1}$ of data collected with the D0 detector at the Fermilab Tevatron Collider at a center-of-mass energy of …

Experimental Discrimination between Charge 2e/3 Top Quark and Charge 4e/3 Exotic Quark Production Scenarios

V. M. Abazov, B. Abbott, M. Abolins, B. S. Acharya et autres

We present the first experimental discrimination between the 2e/3 and 4e/3 top quark electric charge scenarios, using top quark pairs (tt) produced in pp collisions at (square root) s = 1.96 TeV by the Fermilab Tevatron Collider. We use 370 pb;{-1} of …

Measurement of the Bs0 Lifetime Using Semileptonic Decays

V. M. Abazov, B. Abbott, M. Abolins, B. S. Acharya et autres

We report a measurement of the ${B}_{s}^{0}$ lifetime in the semileptonic decay channel ${B}_{s}^{0}\ensuremath{\rightarrow}{D}_{s}^{\ensuremath{-}}{\ensuremath{\mu}}^{+}\ensuremath{\nu}X$ (and its charge conjugate), using approximately $0.4\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of data collected with the D0 detector during 2002--2004. Using 5176 reconstructed ${D}_{s}^{\ensuremath{-}}{\ensuremath{\mu}}^{+}$ signal events, we have measured the …

Search for Pair Production of Scalar Bottom Quarks in pp¯ Collisions at s=1.96 TeV

V. M. Abazov, B. Abbott, M. Abolins, B. S. Acharya et autres

A search for direct production of scalar bottom quarks ($\stackrel{\texttildelow{}}{b}$) is performed with $310\text{ }\text{ }{\mathrm{pb}}^{\ensuremath{-}1}$ of data collected by the D0 experiment in $p\overline{p}$ collisions at $\sqrt{s}=1.96\text{ }\text{ }\mathrm{TeV}$ at the Fermilab Tevatron Collider. The topology analyzed consists of two $b$ …
