چکیده
Abstract We review lattice results related to pion, kaon, D -meson, B and nucleon physics with the aim of making them easily accessible nuclear particle communities. More specifically, we report on determination light-quark masses, form factor $$f_+(0)$$ f + ( 0 ) arising in semileptonic $$K \rightarrow \pi $$ K → π transition at zero momentum transfer, as well decay constant ratio $$f_K/f_\pi / its consequences for CKM matrix elements $$V_{us}$$ V us $$V_{ud}$$ ud . Furthermore, describe obtained some low-energy constants $$SU(2)_L\times SU(2)_R$$ S U 2 L × R $$SU(3)_L\times SU(3)_R$$ 3 Chiral Perturbation Theory. $$B_K$$ B parameter neutral kaon mixing additional four parameters that arise theories beyond Standard Model. For heavy-quark sector, provide $$m_c$$ m c $$m_b$$ b those constants, factors, charmed bottom mesons baryons. These are quantities most relevant global unitarity-triangle fit. status determinations strong coupling $$\alpha _s$$ α s consider elements, axial, scalar tensor bilinears, both isovector flavor diagonal. Finally, this have added a new section reviewing scale-setting quantities.

1.1. QCoh on a stack. We know that QCoh forms a stack, i.e., sheaf of groupoids, over Schfpqc(S) for any scheme S. Thus if we have an fpqc sheaf of groupoids X over S, we can define QCoh(X ) as maps of sheaves X → QCoh on Schfpqc(S). By 2-Yoneda, this definition agrees with the usual notion of quasicoherent sheaves if X is a scheme. For various other (usually equivalent) definitions in the case...

Asymptotic extremal combinatorics deals with questions that in the language of model theory can be re-stated as follows. For finite models M, N of an universal theory without constants and function symbols (like graphs, digraphs or hypergraphs), let p(M, N) be the probability that a randomly chosen sub-model of N with |M | elements is isomorphic to M . Which asymptotic relations exist between t...

This paper deenes for each object X that can be constructed out of a nite number of vertices and cells a vector fX lying in a nite dimensional vector space. This is the ag vector of X. It is hoped that the quantum topological invariants of a manifold M can be expressed as linear functions of the ag vector of the i-graph that arises from any suitable triangulation T of M. Flag vectors are also d...
