The effect of new update of Beta Factory SIA data on Kaon Fragmentation Function

School
PARTICLES AND ACCELERATORS

Abstract:

For the first time we investigate the role of new update of Belle single-inclusive annihilation data on Kaon Fragmentation Function. This analysis was implemented as an open-source framework (xFitter). This study incorporates a comprehensive and up-to-date set of Kaon production data from (SIA) processes, together with the most recent measurements of inclusive cross-sections of single Kaon by the BELLE collaboration. The determination of Kaon FFs along with their theoretical uncertainties is performed in the zero-mass variable-flavor number scheme (ZM-VFNS). The resulting NLO and NNLO Kaon FFs provide valuable insight ...

From the geocentric to the heliocentric and back to

School
ASTRONOMY

Human history is rich in models for the universe, but most of them did not pass the verification tests. Starting with the geocentric, then the heliocentric and finally, the current standard model of cosmology. The latter is a mathematically and physically sophisticated model which relies, among others, on inflation, dark matter and dark energy. These were invoked solely to compete with observations, though, after dozens of years, these ingredients still serve as mathematical terms, with no whatsoever evidence for their existence in nature. And as if that was not enough, several recent observational data appear to be in conflict with the model ...

The Calabi Problem for Fano Threefolds

School
MATHEMATICS

The Calabi Problem is a formidable problem in the confluence of differential and algebraic geometry. It asks which compact complex manifolds admit a Kahler-Einstein metric. A necessary condition for the existence of such a metric is that the canonical class of the manifold has a definite sign. For manifolds with zero or positive canonical class, the Calabi problem was solved by Yau and Aubin/Yau in the 1970s. They confirmed Calabi's prediction, showing that these manifolds always admit a Kahler-Einstein metric. On the other hand, for projective manifolds with negative canonical class, called ''Fano manifolds'', the problem is much more subtle ...
