Signals for CPT and Lorentz Violation in Neutral-Meson Oscillations [PDF]
, 1999 Experimental signals for indirect CPT violation in the neutral-meson systems are studied in the context of a general CPT- and Lorentz-violating standard-model extension.

Can co-location be used as a proxy for face-to-face contacts?
EPJ Data Science, 2018 Technological advances have led to a strong increase in the number of data collection efforts aimed at measuring co-presence of individuals at different spatial resolutions.

No Time Asymmetry from Quantum Mechanics [PDF]
, 1993 With CPT-invariant initial conditions that commute with CPT-invariant final conditions, the respective probabilities (when defined) of a set of histories and its CPT reverse are equal, giving a CPT-symmetric universe.

Journal of Political Ecology, 2022 Latin America has a long history of extractive and exploitative territorial activities, dating back to the colonial era. However, in the last decade there has been a steep increase in these activities, and in socio-environmental conflicts, in Latin ...

Lorentz and CPT Violation in the Higgs Sector [PDF]
, 2004 Colladay and Kostelecky have proposed a framework for studying Lorentz and CPT violation in a natural extension of the Standard Model. Although numerous bounds exist on the Lorentz and CPT violating parameters in the gauge boson and fermion sectors ...

Determination of Vibro - Compaction Parameters by Making a Test Board in a Port Site in Morocco
Civil and Environmental Engineering, 2023 Vibro-compaction is a recent technique for treating soils in the mass, thus improving its mediocre geo mechanical properties. In addition, this treatment makes it possible to minimize the risk of liquefaction, it is closely linked to the grain size of ...

Discreteness Unravels the Black Hole Information Puzzle: Insights from a Quantum Gravity Toy Model
Entropy, 2023 The black hole information puzzle can be resolved if two conditions are met. The first is that the information about what falls inside a black hole remains encoded in degrees of freedom that persist after the black hole completely evaporates.

Sensitivity of CPT Tests with Neutral Mesons [PDF]
, 1998 The sensitivity of experiments with neutral mesons to possible indirect CPT violation is examined. It is shown that experiments conventionally regarded as equivalent can have CPT reaches differing by orders of magnitude within the framework of a minimal ...

CPT Violation Implies Violation of Lorentz Invariance [PDF]
, 2002 An interacting theory that violates CPT invariance necessarily violates Lorentz invariance. On the other hand, CPT invariance is not sufficient for out-of-cone Lorentz invariance.
