Black hole production and large extra dimensions

Area of Science:

• High-energy particle physics
• Theoretical physics
• Cosmology

Background:

• Black hole production at colliders is theoretically possible at the TeV scale in models with large extra dimensions.
• Collider experiments offer a potential avenue to probe physics beyond the Standard Model, including phenomena like black hole creation.

Purpose of the Study:

• To investigate the production mechanisms of black holes at particle colliders.
• To identify and characterize the distinctive signatures resulting from black hole decay events.
• To explore the feasibility of detecting such events in collider data.

Main Methods:

• Analysis of " ij-->BH+others" subprocesses for black hole production.
• Simulation of black hole decay signatures, focusing on particle multiplicity and transverse momentum.
• Identification of specific event characteristics, such as boosted spherical particle distributions and high-transverse-momentum partons.

Main Results:

• Black hole production can occur when colliding energies exceed the Planck scale, effectively at the TeV scale in specific theoretical models.
• Black hole decay produces a unique signature: a high-multiplicity, spherical particle distribution on one side of the event, balanced by a few high-transverse-momentum partons on the other.
• These distinct features serve as valuable "tags" for identifying black hole events in collider data.

Conclusions:

• The study highlights specific, detectable signatures for black hole production at colliders.
• The identified signatures, characterized by particle multiplicity and momentum distributions, offer a promising strategy for experimental searches.
• This research contributes to the ongoing quest for physics beyond the Standard Model and the exploration of high-energy phenomena.
