Time-reparametrization invariances, multithermalization and the Parisi scheme
The Parisi scheme for equilibrium and the corresponding slow dynamics with multithermalization - same temperature common to all observables, different temperatures only possible at widely separated timescales – imply one another.

Quantizing Chaplygin Hamiltonizable nonholonomic systems
In this article we develop a quantization procedure for Chaplygin Hamiltonizable nonholonomic systems—mechanical systems subject to non-integrable velocity constraints whose reduced mechanics is Hamiltonian after a suitable time reparametrization—using ...

Perturbative corrections to power suppressed effects in B ¯ $$ \overline{B} $$ → X u ℓν
We compute the O(α s ) corrections to the Wilson coefficients of the dimension five operators in inclusive semileptonic B decays in the limit of a massless final quark.

General fluctuations of the heterotic pure spinor string on curved backgrounds
The general fluctuations, in the form of vertex operators, for the heterotic superstring in the pure spinor formalism are considered. The case of a flat background is reviewed and the case of a curved case is studied.

Reparametrization invariance and partial re-summations of the heavy quark expansion
We extend existing work on reparametrization invariance (RPI) of the heavy-quark expansion (HQE). RPI implies relations between different orders of the HQE.

Climate change in a Point-Over-Threshold model: an example on ocean-wave-storm hazard in NE Spain [PDF]
A reparametrization of the Generalized Pareto Distribution is here proposed. It is suitable to parsimoniously check trend assumptions within a Point-Over-Threshold model of hazardous events.

Reparametrization of n-Flows of Zero Entropy [PDF]
Let ϕ \phi , ψ \psi be two ergodic n-parameter flows which preserve finite probability measures on their spaces X, Y. Let T be a nullset-preserving map: X → Y X\, \to \,Y sending each ϕ \phi -orbit homeomorphically to a ϕ \phi ...

Towards the underlying gauge theory of the pure spinor superstring
Previous attempts to determine the worldsheet origin of the pure spinor formalism were not completely successful, but introduced important concepts that seem to be connected to its fundamental structure, e.g., emergent supersymmetry and the role of ...

Conformal blocks and bilocal vertex operator transition amplitudes
We revisit the construction of the 2d conformal blocks of primary operator four-point functions as bilocal vertex operator correlators. We find an additional interpretation as a path integral over the reparametrizations of an intermediate cylinder.
