Anomalous diffusion of pions at RHIC

After pointing out the difference between normal and anomalous diffusion, we consider a hadron resonance cascade (HRC) model simulation for particle emission at RHIC and point out that rescattering in an expanding hadron resonance gas leads to a heavy tail in the source distribution. The results are compared to recent PHENIX measurements of the tail of the particle emitting source in Au+Au collisions at RHIC. In this context, we show how can one distinguish experimentally the anomalous diffusion of hadrons from a second order QCD phase transition.

Experiences of family members regarding the oral health care of children

Este estudo objetivou verificar a compreensão das experiências dos familiares em relação ao cuidado com a saúde bucal das crianças. É estudo qualitativo, realizado em 2007, em distrito de saúde do município de Ribeirão Preto, SP, com 12 cuidadores. Utilizou-se referencial teórico da vulnerabilidade e a perspectiva hermenêutica. Três categorias empíricas foram elaboradas: os significados do cuidado com a saúde bucal, em busca das causas e da prevenção de agravos bucais e a realidade dos serviços de saúde bucal. Entre outros elementos potencializadores da vulnerabilidade infantil aos agravos bucais, emergiu a supervalorização da causalidade biológica, do atendimento de alta complexidade e da odontologia estética e, entre os protetores, a valorização do saber popular e a integração de ações e conhecimentos profissionais. Aponta-se para a revisão das estratégias de prevenção e promoção de saúde bucal, fornecendo elementos para auxiliar os serviços de saúde a reorganizarem o cuidado com a saúde bucal de crianças.

ANOMALOUS CONTRIBUTIONS TO E+E- -] E+E-L+L- AT HIGH-ENERGIES

We analyze the process e+ e- --> e+ e- gamma-gamma --> e+ e- l+ l- (l = e, mu, tau-leptons) considering several nonstandard contributions in order to search for new physics beyond the standard model. We are able to test compositeness up to the TeV mass scale at LEP II and CLIC energies.

Compositeness effects in the anomalous weak-magnetic moment of leptons

We investigate the effects induced by excited leptons, at the one-loop level, in the anomalous magnetic and weak-magnetic form factors of the leptons. In particular, we compute their contributions to the weak-magnetic moment of the tau lepton, which can be measured on the Z peak, and we compare it with the contributions to g(mu) - 2, measured at low energies.

COMPARISON OF THE ANOMALOUS AND NONANOMALOUS GENERALIZED SCHWINGER MODELS VIA THE FUNCTIONAL FORMALISM

We calculate the Green functions of the two versions of the generalized Schwinger model, the anomalous and the nonanomalous one, in their higher order Lagrangian density form. Furthermore, it is shown through a sequence of transformations that the bosonized Lagrangian density is equivalent to the former, at least for the bosonic correlation functions. The introduction of the sources from the beginning, leading to a gauge-invariant source term, is also considered. It is verified that the two models have the same correlation functions only if the gauge-invariant sector is taken into account. Finally, there is presented a generalization of the Wess-Zumino term, and its physical consequences are studied, in particular the appearance of gauge-dependent massive excitations.

Anomalous transport effects on magnetic field profile in a motional current sheath

The radial magnetic field profile during implosion of a reversed field current sheath in a theta-pinch was investigated through local measurements and simulation of hybrid code. The actual profile was defined by Hermite interpolation polynomial through mean value of the field at discrete radial position of measurements. Simulation profile was provided by the numerical code with appropriate initial conditions. Classical and anomalous collision process were taken in account in the theoretical model. The results indicated that anomalous effects play major role during the implosion phase of current sheath in a slow rising theta pinch device.
