New physics contributions to moments of inclusive b → c semileptonic decays [PDF]

open access: yesJournal of High Energy Physics, 2023
Inclusive semileptonic B → X c ℓ ν ¯ ℓ $$ {X}_c\ell {\overline{\nu}}_{\ell } $$ decays, where ℓ = μ, e, are by now standard candles in the determination of the CKM element |V cb |. These determinations rely on the heavy-quark expansion and use moments of

The Physics of spectral invariants [PDF]

open access: yes2010 2nd Workshop on Hyperspectral Image and Signal Processing: Evolution in Remote Sensing, 2010
To make full use of the increased possibilities of imaging spectroscopy (compared with the traditional multispectral instruments) for remote sensing of vegetation canopies, physically-based models should be used. The problem of retrieving the large number of model parameters from remotely sensed reflectance data is an ill-posed and underdetermined one.

On the physics of the minimal length: The question of gauge invariance [PDF]

open access: yesInternational Journal of Modern Physics A, 2016
In this note we discuss the question of gauge invariance in the presence of a minimal length. This contribution is prepared for the celebration of the 60th anniversary of the Yang–Mills theory.

A signature invariant geometric algebra framework for spacetime physics and its applications in relativistic dynamics of a massive particle and gyroscopic precession

open access: yesScientific Reports, 2022
A signature invariant geometric algebra framework for spacetime physics is formulated. By following the original idea of David Hestenes in the spacetime algebra of signature $$(+,-,-,-)$$ ( + , - , - , - ) , the techniques related to relative vector and ...

Communication: Fitting potential energy surfaces with fundamental invariant neural network [PDF]

open access: yes, 2016
A more flexible neural network (NN) method using the fundamental invariants (FIs) as the input vector is proposed in the construction of potential energy surfaces for molecular systems involving identical atoms.

Gauge invariant accounts of the Higgs mechanism [PDF]

open access: yes, 2011
The Higgs mechanism gives mass to Yang-Mills gauge bosons. According to the conventional wisdom, this happens through the spontaneous breaking of gauge symmetry.

Invariant differential operators [PDF]

open access: yes, 2016
With applications in quantum field theory, elementary particle physics and general relativity, this two-volume work studies invariance of differential operators under Lie algebras, quantum groups, superalgebras including infinite-dimensional cases ...

Lattice gauge tensor networks

open access: yesNew Journal of Physics, 2014
We present a unified framework to describe lattice gauge theories by means of tensor networks: this framework is efficient as it exploits the high local symmetry content native to these systems by describing only the gauge invariant subspace. Compared to

Invariant representation of physical stability in the human brain [PDF]

open access: yeseLife, 2021
Successful engagement with the world requires the ability to predict what will happen next. Here, we investigate how the brain makes a fundamental prediction about the physical world: whether the situation in front of us is stable, and hence likely to stay the same, or unstable, and hence likely to change in the immediate future.
