    U(1) Chiral Gauge Theory with Domain Wall Fermions and Gauge Fixing

    Get PDF
    We investigate a U(1) lattice chiral gauge theory with the waveguide formulation of the domain wall fermions and with compact gauge fixing. In the reduced model limit, there seems to be no mirror chiral modes at the waveguide boundary.Comment: LATTICE99 (chiral gauge theories), 3 pages, 3 figure

    Chiral Gauge Theory on Lattice with Domain Wall Fermions

    Full text link
    We investigate a U(1) lattice chiral gauge theory with domain wall fermions and compact gauge fixing. In the reduced model limit, our perturbative and numerical investigations show that there exist no extra mirror chiral modes. The longitudinal gauge degrees of freedom have no effect on the free domain wall fermion spectrum consisting of opposite chiral modes at the domain wall and at the anti-domain wall which have an exponentially damped overlap.Comment: 16 pages revtex, 5 postscript figures, PRD versio

    On central tendency and dispersion measures for intervals and hypercubes

    Get PDF
    The uncertainty or the variability of the data may be treated by considering, rather than a single value for each data, the interval of values in which it may fall. This paper studies the derivation of basic description statistics for interval-valued datasets. We propose a geometrical approach in the determination of summary statistics (central tendency and dispersion measures) for interval-valued variables

    Staying Positive: Women's illness narratives and the stigmatized vernacular

    Get PDF
    This article uses the stigmatized vernacular (Goldstein & Shuman, 2012) as a conceptual framework for examining the public construction and reception of women’s illness narratives. I begin by making the case that personal illness narratives – a genre that works to translate the subjective illness experience to a public audience – are rich sites for exploring how discourses of veneration and repudiation can become inextricably intertwined.  Discussing illustrative examples of the construction and reception of women’s illness narratives shared in contexts of breast cancer and fibromyalgia, I show how popular understandings of emotions, particularly positive emotions like happiness, play a major role in the regimes of value shaping how women’s illness experiences become tellable or untellable, and thereby valued or devalued.  Integrating scholarship on illness narratives, stigma, and happiness, I aim to contribute to a richer and more multifaceted view of the illness narrative genre and the discursive contagion of stigma

    Two-Higgs-Doublet type-II and -III models and tcht\to c h at the LHC

    We study the constraints of the generic two-Higgs-doublet model (2HDM) type-III and the impacts of the new Yukawa couplings. For comparisons, we revisit the analysis in the 2HDM type-II. To understand the influence of all involving free parameters and to realize their correlations, we employ χ\chi-square fitting approach by including theoretical and experimental constraints, such as S, T, and U oblique parameters, the production of standard model Higgs and its decay to γγ\gamma\gamma, WW/ZZWW^*/ZZ^*, τ+τ\tau^+\tau^-, etc. The errors of analysis are taken at 68%68\%, 95.5%95.5\%, and 99.7%99.7\% confidence levels. Due to the new Yukawa couplings being associated with cos(βα)\cos(\beta-\alpha) and sin(βα)\sin(\beta -\alpha), we find that the allowed regions for sinα\sin\alpha and tanβ\tan\beta in the type-III model can be broader when the dictated parameter χF\chi_F is positive; however, for negative χF\chi_F, the limits are stricter than those in the type-II model. By using the constrained parameters, we find that the deviation from the SM in the hZγh\to Z\gamma can be of O(10%){\cal O}(10\%). Additionally, we also study the top-quark flavor-changing processes induced at the tree level in the type-III model and find that when all current experimental data are considered, we get Br(tc(h,H))<103Br(t\to c(h, H) )< 10^{-3} for mh=125.36m_h=125.36 and mH=150m_H=150 GeV and Br(tcA)Br(t\to cA) slightly exceeds 10310^{-3} for mA=130m_A =130 GeV.Comment: 22 pages, 11 figures. v3: Slight change in the abstract, Figure.1 added and commented, the conclusion remains unchange
