Although numerical procedures often supply a required accuracy, closed-form expressions allow one to escape any accumulation of errors. In this paper, we discuss the possibility of obtaining explicit results for a variance gamma process. We derive the exact distribution of the maximum of the variance...
has a Chi-square distribution with degrees of freedom. If is a strictly positive constant, then the random variable defined as has a Gamma distribution with parameters and . Therefore, a Gamma variable with parameters and can also be written as the sum of the squares of ...
We describe in detail the method we have used to determine the CKM angles gamma, alpha and beta using flavour symmetries between non-leptonic B decays. This method is valid in the context of the SM but also in presence of New Physics not affecting the amplitudes. 关键词: High Energy Physic...
