چکیده

A bstract We report consistent results for ?( h ? ?? ), $$ \sigma \left(\mathcal{GG}\to h\right) ? GG ? h and \Gamma \left(h\to \mathcal{GG}\right) ? in the Standard Model Effective Field Theory (SMEFT) perturbing SM by corrections \mathcal{O}\left({\overline{\upsilon}}_T^2/16{\pi}^2{\Lambda}^2\right) O ? ¯ T 2 / 16 ? ? Background Method (BFM) approach to gauge fixing, \mathcal{O}\left({\overline{\upsilon}}_T^4/{\Lambda}^4\right) 4 using geometric formulation of SMEFT. combine modify recent literature into a complete set results, uniforming conventions, simultaneously one loop these processes BFM. emphasize calculational scheme dependence present across processes, how operator expansions are not independent beyond leading order. illustrate several cross checks consistency results.

Higher Order Moments and Recurrence Relations of Order Statistics from the Exponentiated Gamma Distribution

Order statistics arising from exponentiated gamma (EG) distribution are considered. Closed from expressions for the single and double moments of order statistics are derived. Measures of skewness and kurtosis of the probability density function of the rth order statistic for different choices of r, n and /theta are presented. Recurrence relations between single and double moments of r...

Testing behavioral game theory: higher-order rationality and consistent beliefs

This paper investigates the behavioral and experimental support for different epistemic conditions that form the foundations of several game theoretic solution concepts. It employs strategic choice data from a carefully chosen set of ringnetwork games to obtain individual-level estimates of the following epistemic conditions: rationality; beliefs about the rationality of others; and consistent ...

Higher Order Sigma-Delta Modulator Interfaces for MEMS Capacitive Sensors

MEMS capacitive sensors, such as pressure sensors, accelerometers and gyroscopes have been one of the most successful examples of microsystem technology. They are routinely used in many applications; the most important being automotive safety systems. These sensors are typically openloop and have low to medium performance specifications. Recently, there has been an emerging requirement for high...

An ${cal O}(h^{8})$ optimal B-spline collocation for solving higher order boundary value problems

As we know the approximation solution of seventh order two points boundary value problems based on B-spline of degree eight has only ${cal O}(h^{2})$ accuracy and this approximation is non-optimal. In this work, we obtain an optimal spline collocation method for solving the general nonlinear seventh order two points boundary value problems. The ${cal O}(h^{8})$ convergence analysis, mainly base...
