Theoretical Overview on the Flavor Issues of Massive Neutrinos

We present an overview on some basic properties of massive neutrinos and focus on their flavor issues, including the mass spectrum, flavor mixing pattern and CP violation. The lepton flavor structures are explored by taking account of the observed value of the smallest neutrino mixing angle \theta_{13}. The impact of \theta_{13} on the running behaviors of other flavor mixing parameters is discussed in some detail. The seesaw-induced enhancement of the electromagnetic dipole moments for three Majorana neutrinos is also discussed in a TeV seesaw scenario.Comment: References added. arXiv admin note: text overlap with arXiv:1203.1672, arXiv:1201.2543, arXiv:1203.311

The order analysis for the two loop corrections to lepton MDM

The experimental data of the magnetic dipole moment(MDM) of lepton($e$, $\mu$) is very exact. The deviation between the experimental data and the standard model prediction maybe come from new physics contribution. In the supersymmetric models, there are very many two loop diagrams contributing to the lepton MDM. In supersymmetric models, we suppose two mass scales $M_{SH}$ and $M$ with $M_{SH}\gg M$ for supersymmetric particles. Squarks belong to $M_{SH}$ and the other supersymmetric particles belong to $M$. We analyze the order of the contributions from the two loop diagrams. The two loop triangle diagrams corresponding to the two loop self-energy diagram satisfy Ward-identity, and their contributions possess particular factors. This work can help to distinguish the important two loop diagrams giving corrections to lepton MDM.Comment: 12 pages, 3 figure

The naturalness in the BLMSSM and B-LSSM

In order to interpret the Higgs mass and its decays more naturally, we hope to intrude the BLMSSM and B-LSSM. In the both models, the right-handed neutrino superfields are introduced to better explain the neutrino mass problems. In addition, there are other superfields considered to make these models more natural than MSSM. In this paper, the method of $\chi^2$ analyses will be adopted in the BLMSSM and B-LSSM to calculate the Higgs mass, Higgs decays and muon $g-2$. With the fine-tuning in the region $0.67\%-2.5\%$ and $0.67\%-5\%$, we can obtain the reasonable theoretical values that are in accordance with the experimental results respectively in the BLMSSM and B-LSSM. Meanwhile, the best-fitted benchmark points in the BLMSSM and B-LSSM will be acquired at minimal $(\chi^{BL}_{min})^2 = 2.34736$ and $(\chi^{B-L}_{min})^2 = 2.47754$, respectively

Job evaluation model of major public hospitals in China

The current economic climate has contributed to an increasingly competitive environment among organizations. In order to ensure competitive advantage, they must be able to promote high levels of professional performance. This research is part of this theme and aims to analyze how the job characteristics, professional knowledge, skills, competencies, training and work engagement influence the job evaluation and, consequently, the performance of employees of six public hospitals, China. The sample consists of 546 subjects aged between 21 and 58 years (M = 37.9; SD = 8.73), with the majority being females (55.5%). For the collection of data, such scales were used as the Job Diagnostic Survey (JDS), the Knowledge, Skills, Abilities, and Other Personal Characteristics Scale (KSAOS), the Competencies and Training Scale (CTS) and the Utrecht Work Engagement Scale (UWES). The results obtained show that the job characteristics, the professional knowledge, the skills, the training and the work engagement influence the job evaluation. It was also found that the male respondents, those belonging to the older age group, those with higher academic qualifications and those with higher positions present higher average performance in all dimensions under study. It was also possible to verify that Autonomy is the JDS variable with greater effect on the Job evaluation and the bigger the Autonomy, Skill variety and Feedback given to the employees, the more positive their perception of Job evaluation. Data analysis also reveals that KSAO moderate the relations between job characteristics and job evaluation and the dimension with the most effect on Job evaluation is Professional Ethics and Health Law. On the other hand, the higher the competencies and professional training in the area of Organization and finance, the greater the Job evaluation. Finally, it was verified that Vigor is the only variable with significant effect on Job evaluation. It is hoped that these results may inspire further research that contributes to a better understanding of these relationships; and at the practical level, it is intended to alert the justified investment by the organizations in the implementation of a performance evaluation model. Taking into account the current competitiveness at the organizational level, it is considered that the analysis of the relationships between these dimensions is crucial to an organization. In this way, this project is intended to build a new process of performance evaluation in public hospitals in China, based on the competencies identified for each job.Atualmente, o clima económico contribuiu para um ambiente cada vez mais competitivo entre as organizações e para garantir a vantagem competitiva, as organizações devem ser capazes de promover altos níveis de desempenho profissional. Esta investigação insere-se nesta temática e tem como objetivo estudar como as características da função, o conhecimento profissional, as habilidades, as competências e o envolvimento no trabalho influenciam a avaliação do trabalho e, consequentemente, o desempenho dos funcionários de seis hospitais públicos . China. A amostra é composta por 546 sujeitos com idades compreendidas entre os 21 e os 58 anos (M = 37.9; DP = 8.73), sendo a maioria do sexo feminino (55.5%). Os dados foram recolhidos através das seguintes escalas: Job Diagnostic Survey (JDS), Escala de Conhecimento, Habilidades, Aptidões e Outras Escalas Pessoais (KSAOS), Escala de Competências e Formação (CTS) e Escala de Envolvimento no Trabalho de Utrecht ( UWES). Os resultados obtidos mostram que as características da função, o conhecimento profissional, as habilidades, a formação e o envolvimento no trabalho influenciam a avaliação do trabalho. Constatou-se também que os entrevistados do sexo masculino, os que pertencem à faixa etária mais avançada, os que possuem maior qualificação académica e que ocupam posições hierárquicas mais elevadas, apresentam um desempenho médio superior em todas as dimensões em estudo. Também foi possível verificar que a Autonomia é a variável do JDS com maior efeito na avaliação do trabalho e que quanto maior é a Autonomia, a variedade de competências e o feedback dado aos funcionários, mais positiva é a sua perceção da avaliação do trabalho. A análise dos dados também revelou que o KSAO modera a relação existente entre as características da função e a avaliação do trabalho e que a variável com maior efeito na avaliação do trabalho é a Ética Profissional e a Lei da Saúde. Por outro lado, quanto maiores são as competências e a formação profissional na área de Organização e Finanças, melhor é a avaliação do trabalho. Por último, verificou-se que o Vigor é a única dimensão do envolvimento no trabalho com efeito significativo na avaliação do mesmo. Espera-se que esses resultados possam inspirar pesquisas futuras e que possam contribuir para uma melhor compreensão dessas relações; a nível prático pretende-se alertar os gestores para a implementação de um modelo de avaliação de desempenho. Considerando a atual competitividade a nível organizacional, considera-se que a análise da relação entre estas dimensões é crucial para qualquer organização. Esta investigação pretende assim construir um novo processo de avaliação do trabalho nos hospitais públicos na China, com base nas competências identificadas para cada função

Ferromagnetic to antiferromagnetic transition of one-dimensional spinor Bose gases with spin-orbit coupling

We have analytically solved one-dimensional interacting two-component bosonic gases with spin-orbit (SO) coupling by the Bethe-ansatz method. Through a gauge transformation, the effect of SO coupling is incorporated into a spin-dependent twisted boundary condition. Our result shows that the SO coupling can influence the eigenenergy in a periodical pattern. The interplay between interaction and SO coupling may induce the energy level crossing for the ground state, which leads to a transition from the ferromagnetic to antiferromagnetic state.Comment: 6 pages, 4 figure

Associated production of a neutral top-Higgs with a heavy-quark pair in the \gamma\gamma collisions at ILC

We have studied the associated production processes of a neutral top-Higgs in the topcolor assisted technicolor model with a pair of heavy quarks in \gamma\gamma collisions at the International Linear Collider (ILC). We find that the cross section for t\bar{t}h_t in \gamma\gamma collisions is at the level of a few fb with the c.m. energy \sqrt{s}=1000 GeV, which is consistent with the results of the cross section of t\bar{t}H in the standard model and the cross section of t\bar{t}h in the minimal supersymmetric standard modeland the little Higgs models. It should be distinct that hundreds of to thousands of h_t per year can be produced at the ILC, this process of \gamma\gamma \to t\bar{t}h_t is really interesting in testing the standard model and searching the signs of technicolor.Comment: 4 pages, 4 figures, some references are adde
