beta functions of a scalar theory coupled to gravity.
We study a scalar field theory coupled to gravity on a flat background, below Planck's energy. Einstein's theory is treated as an effective field theory. Within the context of Wilson's renormalization group, we compute gravitational corrections to the beta functions and the anomalous dimension of the scalar field, taking into account threshold effects.
Higgs mass predicted from the standard model with asymptotically safe gravity
The aim of this thesis is to predict the Higgs boson mass from the Standard model of particle physics with gravity as an asymptotically safe theory. To reach this goal, the running of four standard model couplings in addition to the Higgs self-coupling is derived at one-loop level in the MS-scheme. Standard model β-functions are supplemented by asymptotically safe gravity corrections at very large energies, and differential equation group of β-functions is solved numerically. At low energies a partial finite renormalisation of the Standard Model is performed to derive the connection between the self-coupling in the MS-scheme and the physical, measurable parameters. Relating the value for the Higgs self-coupling given by the running of couplings to the physical one leads to a prediction λ ≈ 0.131 for the Higgs self-coupling which corresponds to a mass mh ≈ 126GeV. In 2012 at CERN the Higgs mass was measured to be mh ≈ 125GeV corresponding to the value of λ ≈ 0.13 for the self-coupling. The prediction got in this thesis is very close to the measured one when one takes into account that calculations were done only at one-loop level.
Creativity profile of university and conservatory dance students.
What are dance students' creative potential, Special personality characteristics and preferences for high energy activities? Using standardized and original paper and pencil instruments, comparisons were made among dance students in university and conservatory settings, college students and art students. The results demonstrated that dance students are creative, show strong preference for dynamic figures, and have distinct personality characteristics. The university dance students differed from the conservatory students in several important ways.
