I report, emphasizing some key open issues and some aspects that are particularly relevant
for phenomenology, on the status of the development of “doubly-special” relativistic (“DSR”) …

Strongest atomic physics bounds on noncommutative quantum gravity models

K Piscicchia, A Addazi, A Marcianò, M Bazzi… - Physical Review Letters, 2022 - APS
Investigations of possible violations of the Pauli exclusion principle represent critical tests of
the microscopic space-time structure and properties. Space-time noncommutativity provides …

Loop quantum gravity phenomenology: Linking loops to observational physics

F Girelli, F Hinterleitner, SA Major - SIGMA. Symmetry, Integrability and …, 2012 - emis.de
Research during the last decade demonstrates that effects originating on the Planck scale
are currently being tested in multiple observational contexts. In this review we discuss …

Quantum black hole in the generalized uncertainty principle framework

A Bina, S Jalalzadeh, A Moslehi - … Review D—Particles, Fields, Gravitation, and …, 2010 - APS
