Dust collapse and bounce in spherically symmetric quantum-inspired gravity models
Douglas M. Gingrich
We develop an algebraic equation to describe the collapse and possible bounce of dust in quantum-inspired gravity models with spherical symmetry from knowledge of the vacuum soluti…
Canonical form of a deformed Poisson bracket spacetime
Douglas M. Gingrich
The general uncertainty principle applied to gravity can be implemented as a set of modified Poisson brackets in the canonical formalism. As such, the theory is not canonical and t…
Geometry of a generalized uncertainty-inspired spacetime
Douglas M. Gingrich, Saeed Rastgoo
We examine the geometry of a generalized uncertainty-inspired quantum black hole. The diagonal line element is not - symmetric, i.e. , which leads to an…
A generalized uncertainty-inspired quantum black hole
Federica Fragomeno, Douglas M. Gingrich, Samantha Hergott +2
We derive the full spacetime metric of a generalized uncertainty-inspired quantum black hole. We examine a previous model of the interior in this approach and show that extending i…
Measurement of the branching fraction of the decay at Belle II
Belle II Collaboration, I. Adachi, L. Aggarwal +389
We measure the branching fraction of the decay using data collected with the Belle II detector. The data contain 387 million pairs produced i…
Quasinormal modes of a nonsingular spherically symmetric black hole effective model with holonomy corrections
Douglas M. Gingrich
We calculate the quasinormal modes of a nonsingular spherically symmetric black hole effective model with holonomy corrections. The model is based on quantum corrections inspired b…
Quasinormal modes of loop quantum black holes near the Planck scale
Douglas M. Gingrich
We compare four loop quantum gravity inspired black hole metrics near the Planck scale. Spin 0, 1/2, 1, and 2 field perturbations on these backgrounds are studied. The axial gravit…

Douglas M. Gingrich
Quantum atmosphere effective radii for the emission of spin-0, -1/2, -1, and -2 massless fields from Schwarzschild, Tangherlini, non-commutative geometry inspired, and polymeric bl…
Greybody factors for higher-dimensional non-commutative geometry inspired black holes
Zachary Cox, Douglas M. Gingrich
Greybody factors are computed for massless fields of spin 0, 1/2, 1, and 2 emitted from higher-dimensional non-commutative geometry inspired black holes. Short-range potentials are…
Quantum black holes in the horizon quantum mechanics model at the Large Hadron Collider
Douglas M. Gingrich, Brennan Undseth
Quantum black hole production at the Large Hadron Collider is investigated using the horizon quantum mechanics model. This model has novel implications for how black holes might be…
Monte Carlo event generator for the production and decay of string resonances in proton-proton collisions
Pourya Vakilipourtakalou, Douglas M. Gingrich
We describe a Monte Carlo event generator for the production and decay of first and second string resonances through 2 2 partonic and also 2-parton -…
A Roadmap for HEP Software and Computing R&D for the 2020s
Johannes Albrecht, Antonio Augusto Alves, Guilherme Amadio +307
Particle physics has an ambitious and broad experimental programme for the coming decades. This programme requires large investments in detector hardware, either to build new facil…
Collider searches for non-perturbative low-scale gravity states
Douglas M. Gingrich
The possibility of producing non-perturbative low-scale gravity states in collider experiments was first discussed in about 1998. The ATLAS and CMS experiments have searched for no…
Experimental limits on the fundamental Planck scale in large extra dimensions
Douglas M. Gingrich
I present an up to date set of limits on the fundamental Planck scale M_D. The best limit for each number of extra dimensions n is shown in bold font. For n = 2, M_D > 5.6 TeV; n =…
Noncommutative geometry inspired black holes in higher dimensions at the LHC
Douglas M. Gingrich
When embedding models of noncommutative geometry inspired black holes into the peridium of large extra dimensions, it is natural to relate the noncommutativity scale to the higher-…
Production of tidal-charged black holes at the Large Hadron Collider
Douglas M. Gingrich
Tidal-charged black hole solutions localized on a three-brane in the five-dimensional gravity scenario of Randall and Sundrum have been known for some time. The solutions have been…
Quantum black holes with charge, colour, and spin at the LHC
Douglas M. Gingrich
In low-scale gravity scenarios, quantum black holes could be produced at the Large Hadron Collider (LHC) provided the Planck scale is not higher than a few TeV. Based on fundamenta…

We describe the Monte Carlo event generator for quantum black hole production and decay in proton-proton collisions -- QBH version 1.03.
Signatures of Singlet Neutrinos in Large Extra Dimensions at the LHC
Douglas M. Gingrich
It is a challenge to explain why neutrinos are so light compared to other leptons. Small neutrino masses can be explained if right-handed fermions propagate in large extra dimensio…

We have used the STACEE high-energy gamma-ray detector to look for fast blue-green laser pulses from the vicinity of 187 stars. The STACEE detector offers unprecedented light-colle…
Black Hole Production at the Large Hadron Collider
Douglas M. Gingrich
Black hole production at the Large Hadron Collider (LHC) is an interesting consequence of TeV-scale gravity models. The predicted values, or lower limits, for the fundamental Planc…
