BMSSM Implications for Cosmology

The addition of non-renormalizable terms involving the Higgs fields to the MSSM (BMSSM) ameliorates the little hierarchy problem of the MSSM. We analyze in detail the two main cosmological issues affected by the BMSSM: dark matter and baryogenesis. The regions for which the relic abundance of the LSP is consistent with WMAP and collider constraints are identified, showing that the bulk region and other previously excluded regions are now permitted. Requiring vacuum stability limits the allowed regions. Based on a two-loop finite temperature effective potential analysis, we show that the electroweak phase transition can be sufficiently first order in regions that for the MSSM are incompatible with the LEP Higgs mass bound, including parameter values of \tan\beta \lsim 5, m_{\tilde{t}_{1}} > m_t, m_Q << TeV.Comment: 28 pages, 4 figures.

The non-zero baryon number formulation of QCD

We discuss the non-zero baryon number formulation of QCD in the quenched limit at finite temperature. This describes the thermodynamics of gluons in the background of static quark sources. Although a sign problem remains in this theory, our simulation results show that it can be handled quite well numerically. The transition region gets shifted to smaller temperatures and the transition region broadens with increasing baryon number. Although the action is in our formulation explicitly Z(3) symmetric the Polyakov loop expectation value becomes non-zero already in the low temperature phase and the heavy quark potential gets screened at non-vanishing number density already this phase.Comment: LATTICE99(Finite Temperature and Density), Latex2e using espcrc2.sty, 3 pages, 7 figure

Optimierung von Saatzeitpunkt und Nährstoffversorgung von Wintermohn

Der optimale Saatzeitpunkt sowie die optimale Stickstoffversorgung von Speisemohn (Papaver somniferum L.) werfen insbesondere im Winteranbau Fragen auf. In einem Feldversuch wurde 2017 die Wintermohnsorte ‘Zeno Morphex’ zu zwei verschiedenen Saatterminen im Herbst ausgesät. Eine Düngung mit Stickstoff erfolgte im Frühjahr in den Stufen 30 kg N ha-1 und 80 kg N ha-1 in Form von Hornmehl und Hornspänen. Der Saatzeitpunkt hatte keinen Einfluss auf den Samenertrag, auch die Anzahl Kapseln je Pflanze variierte kaum. Die Düngung mit 80 kg N ha-1 erhöhte im Vergleich zur Düngehöhe 30 kg N ha-1 den Samenertrag signifikant (Maximalertrag: Ø 1342,24 kg ha-1, Minimalertrag: Ø 806,33 kg ha-1). Ebenso wiesen die mit Hornmehl gedüngten Varianten siginifikant höhere Samenerträge auf als die Varianten, die Hornspäne erhielten

Solution of the Complex Action Problem in the Potts Model for Dense QCD

Monte Carlo simulations of lattice QCD at non-zero baryon chemical potential $\mu$ suffer from the notorious complex action problem. We consider QCD with static quarks coupled to a large chemical potential. This leaves us with an SU(3) Yang-Mills theory with a complex action containing the Polyakov loop. Close to the deconfinement phase transition the qualitative features of this theory, in particular its Z(3) symmetry properties, are captured by the 3-d 3-state Potts model. We solve the complex action problem in the Potts model by using a cluster algorithm. The improved estimator for the $\mu$-dependent part of the Boltzmann factor is real and positive and is used for importance sampling. We localize the critical endpoint of the first order deconfinement phase transition line and find consistency with universal 3-d Ising behavior. We also calculate the static quark-quark, quark-anti-quark, and anti-quark-anti-quark potentials which show screening as expected for a system with non-zero baryon density.Comment: 28 pages, 7 figure

CLINICAL METHOD: MORAL DEVELOPMENT IN QUILOMBOLAS

O presente trabalho traz reflexões preliminares de estudo teórico e exploratório por método clinico realizado em escolas da Colônia Vitória, município de Guarapuava, estado do Paraná, Brasil que recebem crianças advindas da comunidade quilombola Invernada Paiol de Telha. Pretende-se refletir sobre esse método por meio da compreensão moral ambiental dessas crianças quilombolas. Baseados na obra do autor construtivista Jean Piaget e considerando a percepção ambiental como parte da conexão existente entre a formação do juízo moral e dos valores quilombolas que são construídos de forma a existir uma compreensão do meio ambiente enquanto meio onde há uma relação dinâmica de troca. Entende-se que o método clínico viabilizou essa analise quando colocou em movimento o pensar infantil ativando o julgamento moral para as questões ambientais e também quando evindenciou o silêncio por opressão vivida pelas meninas da comunidade.The present work brings preliminary reflections of theoretical and exploratory study by clinical method carried out in schools in Colônia Vitória, municipality of Guarapuava, state of Paraná, Brazil, who receive children from the quilombola community, Invernada Paiol de Telha. It is intended to reflect on this method through the environmental moral understanding of these quilombola children. Based on the work of constructivist author Jean Piaget and considering environmental perception as part of the connection between the formation of moral judgment and quilombola values that are built so that there is an understanding of the environment as a medium where there is a dynamic exchange relationship. It is understood that the clinical method made this analysis feasible when the children's thinking was set in motion&nbsp;activating the moral judgment for environmental issues and also when the silence of oppression experienced by the girls in the community was evident.

Beyond the MSSM Higgs with d=6 effective operators

We continue a previous study of the MSSM Higgs Lagrangian extended by all effective operators of dimension d=6 that can be present beyond the MSSM, consistent with its symmetries. By supersymmetry, such operators also extend the neutralino and chargino sectors, and the corresponding component fields Lagrangian is computed onshell. The corrections to the neutralino and chargino masses, due to these operators, are computed analytically in function of the MSSM corresponding values. For individual operators, the corrections are small, of few GeV for the constrained MSSM (CMSSM) viable parameter space. We investigate the correction to the lightest Higgs mass, which receives, from individual operators, a supersymmetric correction of up to 4 (6) GeV above the 2-loop leading-log CMSSM value, from those CMSSM phase space points with: EW fine tuning Delta<200, consistent with WMAP relic density (3$\sigma$), and for a scale of the operators of M=10 (8) TeV, respectively. Applied to the CMSSM point of minimal fine tuning (Delta=18), such increase gives an upper limit $m_h=120(122)\pm 2$ GeV, respectively. The increase of m_h from individual operators can be larger ($\sim$ 10-30 GeV) for those CMSSM phase space points with Delta>200; these can now be phenomenologically viable, with reduced Delta, and this includes those points that would have otherwise violated the LEP2 bound by this value. The neutralino/chargino Lagrangian extended by the effective operators can be used in studies of dark matter relic density within extensions of the MSSM, by implementing it in public codes like micrOMEGAs.Comment: 36 pages, Latex, 16 figures (v2: minor changes, corrected typos

Universality and scaling behavior of RG gauge actions

We study universality and scaling properties of RG gauge actions (Iwasaki and DBW2). In the first part we consider the critical temperature T_{c} and compute the reference energy scale r_{0} for critical couplings \beta_{c} corresponding to N_{t}=3,4,6,8. The universality of T_{c}r_{0} between Iwasaki and Wilson action is confirmed and the scaling behavior of the Iwasaki action is found to be better than the one for the Wilson action. The results for the DBW2 action show larger lattice artefacts. A continuum value T_{c}r_{0}=0.7498(50) is extracted. We compute also the glueball masses for the states 0^{++} and 2^{++}, investigate the scaling of m_{0^{++}}r_{0} and m_{2^{++}}r_{0} and point out practical problems which are due to the violation of positivity present in the RG actions.Comment: 36 page

CRIATIVIDADE NA EDUCAÇÃO: PERSPECTIVA COMPLEXA

Apresentamos ensaio teórico para reflexão e crítica relativa à criatividade na educação contemporânea em perspectiva da Teoria de Complexidade. Sob viés filosófico de Edgar Morin pretendemos oferecer conhecimento que coloque em movimento vários elementos complementares, transcendentes e concorrentes antes que se possa afirmar que houve criatividade. Para tanto, nos concentramos na compreensão da pessoa da criatividade, do potencial, dos estímulos, das frustrações, do processo de desenvolvimento, métricas, assim como treino cognitivo e o ambiente escolar.
