“…6,7,11,86 The hoop conjecture has been tested in the context of high-speed collisions of scalar-field 72 and fluid-ball configurations. 87,88 In all these simulations, BH formation is observed at high velocities, consistent with the prediction of the hoop conjecture.…”

We review recent progress in the application of numerical relativity techniques to astrophysics and high-energy physics. We focus on recent developments regarding the spin evolution in black hole binaries, high-energy black hole collisions, compact object solutions in scalar-tensor gravity, superradiant instabilities, hairy black hole solutions in Einstein's gravity coupled to fundamental fields, and the possibility to gain insight into these phenomena using analog gravity models.

“…The exclusions tend to be stronger for higher n, due to the larger signal cross-sections. They also tend to be stronger for the non-rotating case than for the rotating case, due to a larger number of Hawking emissions 9 The combined exclusions use the same thresholds in the two channels. Event Selection leading lepton p T > 100 GeV (flavour defines channel) number of objects above 100 GeV > 2 appropriate p T threshold Table 5.…”

“…In the black hole formation stage, some energy is expected to be lost to gravitational or SM radiation. This has recently been calculated using numerical simulations of general relativity [9].Once a black hole has formed and settled into a Schwarzschild [10] (non-rotating) or Myers-Perry [11] (rotating) state, it is assumed to lose mass and angular momentum through the emission of Hawking radiation [12]. All types of SM particles are emitted, although the graviton emission spectra have been calculated only for the non-rotating case [13,14].…”

A search for an excess of events with multiple high transverse momentum objects including charged leptons and jets is presented, using 20.3 fb −1 of proton-proton collision data recorded by the ATLAS detector at the Large Hadron Collider in 2012 at a centre-of-mass energy of √ s = 8 TeV. No excess of events beyond Standard Model expectations is observed. Using extra-dimensional models for black hole and string ball production and decay, exclusion contours are determined as a function of the mass threshold for production and the fundamental gravity scale for two, four and six extra dimensions. For six extra dimensions, mass thresholds of 4.8-6.2 TeV are excluded at 95% confidence level, depending on the fundamental gravity scale and model assumptions. Upper limits on the fiducial cross-sections for non-Standard Model production of these final states are set. 6 Event selection 8 7 Background estimation 9 7.1 Prompt background estimation from control regions 9 7.2 Backgrounds from misidentified objects and non-prompt leptons 13 7.3 Background smoothing with fits 148 Systematic uncertainties 159 Results and interpretation 17 Summary 25The ATLAS collaboration 32 IntroductionA long-standing problem in particle physics is the very large difference between two apparently fundamental energy scales: the electroweak scale at O(0.1 TeV) and the gravitational (Planck) scale M Pl = O(10 16 TeV). Models postulating extra spatial dimensions into which the gravitational field propagates attempt to address this hierarchy problem [1][2][3][4]. In most of these models, the Standard Model (SM) fields are constrained to the one time and three spatial dimensions of our universe, whilst the gravitons also propagate into the n "bulk" extra dimensions. In these models, the fundamental gravitational scale in the full (n + 4) space-time dimensions, M D , is dramatically lower than M Pl , and represents an effective scale appropriate for probes of the gravitational interactions at low energies. A value of M D in the TeV range would allow for the production of strong gravitational states such as microscopic black holes at energies accessible at the Large Hadron Collider (LHC) [5][6][7]. Two well-motivated extra-dimensional models are those with large flat extra dimensions -1 - JHEP08(2014)103(ADD models [2,3]) and those with small, usually warped, extra dimensions (RS models [4]). This analysis considers ADD models, for which the n = 1 case is ruled out and the n = 2 case is disfavoured by current astrophysical and tabletop experiments [8]. Thus, benchmark models with two, four and six additional spatial dimensions are considered.Estimates of the black hole production cross-sections invoke semiclassical approximations, the validity of which require the production centre-of-mass energy to be significantly above M D . This motivates the introduction of a production mass threshold M th , well above M D . In the black hole formation stage, some energy is expected to be lost to gravitational or SM radiation. This has recently been calcu...

The demand to obtain answers to highly complex problems within strong-field gravity has been met with significant progress in the numerical solution of Einstein’s equations — along with some spectacular results — in various setups.We review techniques for solving Einstein’s equations in generic spacetimes, focusing on fully nonlinear evolutions but also on how to benchmark those results with perturbative approaches. The results address problems in high-energy physics, holography, mathematical physics, fundamental physics, astrophysics and cosmology.
