SoTL in student affairs graduate preparation programs
No full textIn the previous article, we defined the scholarship of teaching and learning (SoTL) and the scholarship of practice (SoP) and identified characteristics and qualities related to these topics. In this article, we provide examples of scholars who have conducted a SoTL project related to student affairs. Each of these entries describes the project and gives us insights into why scholars choose to engage in this work and the impact of their work on teaching and learning.This article is published as Gansemer-Topf, A.

Stereospecific Synthesis of the Saccharosamine-Rhamnose-Fucose Fragment Present in Saccharomicin B
No full textA synthetic route has been developed
for constructing the d-saccharosamine-l-rhamnose-d-fucose (Sac-Rha-Fuc)
trisaccharide fragment present in the antibacterial natural product
saccharomicin B. The Sac monosaccharide was synthesized through a
modified nine step procedure starting from d-rhamnal in 23%
overall yield. 1-O-TBS Sac donors were used to construct
the β-linked Sac-Rha disaccharide. This disaccharide was coupled
to a Fuc acceptor under BSP/Tf2O conditions to afford a
trisaccharide properly functionalized for elaboration to saccharomicin

Tau decays to five and seven charged particles and the tau neutrino mass
No full textThe production of -lepton pairs in e\sp+e\sp- collisions at 29 GeV has been used to study the inclusive decay into five and seven charged particles. The results obtained in this analysis are based on a data sample corresponding to a total integrated luminosity of 300 pb\sp{-1}. Thirteen events are observed in which the decays to five charged particles giving a branching ratio of B( 5\pi\sp\pm\nu\sb\tau + n) = (10.2 2.9) 10\sp{-4}. Six of these events contain neutral energy consistent with a single \pi\sp{o}. With this interpretation the exclusive branching ratios are measured to be B( 5\pi\sp\pm\nu\sb\tau) = (5.1 2.0) 10\sp{-4} and B( 5\pi\sp\pm\pi\sp{o}\nu\sb\tau) = (5.1 2.2) 10\sp{-4}. No decays to seven charged particles were observed giving an upper limit on the branching ratio of B( 7\pi\sp\pm\nu\sb\tau + n) 1.9 10\sp{-4} at the 90% confidence level. This data was used to look for K\sp{o}3\pi\sp\pm\nu\sb\tau + n. No K\sp{o}\u27s were found in the sample of 13 events, yielding an upper limit on the branching ratio of B( K\sp{o}3\pi\sp\pm\nu\sb\tau + n) 2.1 10\sp{-3} at the 90% confidence level. The 5\pi\sp\pm\pi\sp{o} events were also used to place limits on decays involving one or two \u27s. The 90% confidence level upper limits are found to be B( 3\pi\sp\pmn\pi\sp{o}\nu\sb\tau) 0.005 and B( \eta\eta\pi\sp\pmn\pi\sp{o}\nu\sb\tau) 0.007 (n 0). The hadronic mass spectrum of the five-prong events was used to place an upper limit on the mass of the neutrino. At the 95% confidence level the upper limit is M\sb\nu\sb\tau 76MeV/c\sp2
Observation of B-s(0) mesons and measurement of the B-s(0)/B+ yield ratio in PbPb collisions at root S-NN=5.02 TeV
No full textThe Bs0 and B+ production yields are measured in PbPb collisions at a center-of-mass energy per nucleon pair of 5.02 TeV. The data sample, collected with the CMS detector at the LHC, corresponds to an integrated luminosity of 1.7 nb−1. The mesons are reconstructed in the exclusive decay channels B→s0J/ψ(μ+μ−)φ(K+K−) and B→+J/ψ(μ+μ−)K+, in the transverse momentum range 7–50 GeV/c and absolute rapidity 0–2.4. The Bs0 meson is observed with a statistical significance in excess of five standard deviations for the first time in nucleus-nucleus collisions. The measurements are performed as functions of the transverse momentum of the B mesons and of the PbPb collision centrality. The ratio of production yields of Bs0 and B+ is measured and compared to theoretical models that include quark recombination effects
Search for a massive resonance decaying to a pair of Higgs bosons in the four b quark final state in proton-proton collisions at root s=13 TeV
No full textA search for a massive resonance decaying into a pair of standard model Higgs bosons, in a final state consisting of two b quark-antiquark pairs, is performed. A data sample of proton-proton collisions at a centre-of-mass energy of 13 TeV is used, collected by the CMS experiment at the CERN LHC in 2016, and corresponding to an integrated luminosity of 35.9 fb(-1). The Higgs bosons are highly Lorentz-boosted and are each reconstructed as a single large-area jet. The signal is characterized by a peak in the dijet invariant mass distribution, above a background from the standard model multijet production. The observations are consistent with the background expectations, and are interpreted as upper limits on the products of the s-channel production cross sections and branching fractions of narrow bulk gravitons and radions in warped extra-dimensional models. The limits range from 126 to 1.4 fb at 95% confidence level for resonances with masses between 750 and 3000 GeV, and are the most stringent to date, over the explored mass range.

Measurement of the lifetime of hadrons containing the b-quark
No full textData collected with the High Resolution Spectrometer at PEP, corresponding to an integrated luminosity of 200 pb-1 of e+e- annihilation at 29 GeV, were used to measure the mean lifetime of hadrons containing the bottom quark. The lifetime was determined using the impact parameter method on events containing a high-transverse-momentum electron. The result, based on a sample of 301 events, is [tau]B = 1.02 +/-0.390.42 ps, where the indicated errors include both statistics and systematics.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/26581/1/0000120.pd
A Measurement of the inclusive b ---> s gamma branching ratio
No full textThe flavour changing neutral current decay b -> s gamma has been detected in hadronic Z decays collected by ALEPH at LEP. The signal is isolated in lifetime-tagged b-bbar events by the presence of a hard photon associated with a system of high momentum and high rapidity hadrons. The background processes are normalised from the data themselves. The inclusive branching ratio is measured to be 3.11 +- 0.80_stat +- 0.72_syst DistList PSforwarding done files helpND.html images insert_new.sh insert_new.sh~ log modify modifying pending running waiting 10**-4, consistent with the Standa rd Model expectation via penguin processes
