Analyses of multiplicity distributions by means of the Modified Negative Binomial Distribution and its KNO scaling function
We analyze various data of multiplicity distributions by means of the
Modified Negative Binomial Distribution (MNBD) and its KNO scaling function,
since this MNBD explains the oscillating behavior of the cumulant moment
observed in e^+e^- annihilations, h-h collisions and e-p collisions. In the
present analyses, we find that the MNBD(discrete distributions) describes the
data of charged particles in e^+e^- annihilations much better than the Negative
Binomial Distribution (NBD). To investigate stochastic property of the MNBD, we
derive the KNO scaling function from the discrete distribution by using a
straightforward method and the Poisson transform. It is a new KNO function
expressed by the Laguerre polynomials. In analyses of the data by using the KNO
scaling function, we find that the MNBD describes the data better than the
gamma function.Thus, it can be said that the MNBD is one of useful formulas as
well as NBD.Comment: 12 pages, latex, 3 figure
Analysis of Bose-Einstein correlations in e+e- -> W+W- events including final state interactions
Recently DELPHI Collaboration reported new data on Bose-Einstein correlations
(BEC) measured in e+e- -> W^+W^- events. Apparently no enhancement has been
observed. We have analyzed these data including final state interactions (FSI)
of both Coulomb and strong (s-wave) origin and found that there is enhancement
in BEC but it is overshadowed by the FSI which are extremely important for
those events. We have found the following values for the size of the
interaction range beta and the degree of coherence lambda: beta=0.87 +/- 0.31fm
and lambda=1.19 +/- 0.48, respectively.Comment: 7pages, 4 figure
From Revising Program SLOs to a Culture of Open Communication in Dental Hygiene
This poster describes the program student learning outcomes development process in the Dental Hygiene BS degree program. It details the challenges that the program faced in the past, the success strategies to engage faculty, and the benefit of assessment process. The Dental Hygiene BS degree has 16 faculty members, most majority of whom are practitioners as dental hygienists or dentists. Project objectives and the methods of revising Student Learning Outcomes (SLOs) are outlined, a detailed description of Program SLOs is provided, and follow-up actions along with next steps are provided
Angular magnetoresistance oscillations in bilayers in tilted magnetic fields
Angular magnetoresistance oscillations (AMRO) were originally discovered in
organic conductors and then found in many other layered metals. It should be
possible to observe AMRO to semiconducting bilayers as well. Here we present an
intuitive geometrical interpretation of AMRO as the Aharonov-Bohm interference
effect, both in real and momentum spaces, for balanced and imbalanced bilayers.
Applications to the experiments with bilayers in tilted magnetic fields in the
metallic state are discussed. We speculate that AMRO may be also observed when
each layer of the bilayer is in the composite-fermion state.Comment: 4 pages, 5 figures, Proceedings of EP2DS-16. V.2: figures corrected,
