High Energy Physics - Phenomenology
We calculate the complete one-loop electroweak corrections to the inclusive
H→ZZ and H→Zγ decays in the dimension-6
extension of the Standard Model Effective Field Theory (SMEFT). The corrections
to $H\right...

We consider the global evolution problem for Einstein's field equations in
the near-Minkowski regime and study the long-time dynamics of a massive scalar
field evolving under its own gravitational field. We establish the existence of
a glob...
Expansions of Iterated Stratonovich Stochastic Integrals Based on
Generalized Multiple Fourier Series: Multiplicities 1 to 6 and Beyond
December 27, 2017
Mathematics

The article is devoted to the expansions of iterated Stratonovich stochastic
integrals of multiplicities 1 to 6 on the basis of the method of generalized
multiple Fourier series that converge in the sense of norm in Hilbert space

We propose a framework based on the concept of the semigroup to understand
the fermion sign problem. By using properties of contraction semigroups, we
obtain sufficient conditions for quantum lattice fermion models to be
sign-problem-free. ...
Revisiting the charging-capacitor problem

Classical Physics
The charging capacitor is used as a standard paradigm for illustrating the
concept of the Maxwell "displacement current". A certain aspect of the problem,
however, is often overlooked. It concerns the conditions for satisfaction of
the Fara...

We estimate the chemical freeze-out of light nuclear clusters for NICA
energies of above 2 A GeV. On the one hand we use results from the low energy
domain of about 35 A MeV, where medium effects have been shown to be important
to explain e...
Coalgebraic Behavioral Metrics

We study different behavioral metrics, such as those arising from both
branching and linear-time semantics, in a coalgebraic setting. Given a
coalgebra α:X→HX for a functor H:Set→Set, we define...

Conservation of angular momentum depends on the existence of rotational
symmetry. However, even in systems where this symmetry is broken, flipping
between angular momentum eigenstates often requires an activation energy. Here
we discuss an ...
Axiomatic foundation of quantum measurements and survival effect

The axiomatic theory of quantum first-kind measurements is developed in a
rigorous form based on five Postulates. The measurement theory for observable
with continuous spectrum is given in a rigged Hilbert space. This approach also

Homotopical algebra for Lie algebroids

We construct Quillen equivalent semi-model structures on the categories of
dg-Lie algebroids and L∞-algebroids over a commutative dg-algebra in
characteristic zero. This allows one to apply the usual methods of homotopical
algebra t...
