Effective Field Theory for Diffraction—Iain STEWART
A significant fraction of scattering events at colliders are diffractive, with large angular gaps devoid of particles. Unlike the primary hard scattering processes studied at hadron colliders, so far a first principle theoretical description of these diffractive events has been lacking. These diffractive processes are believed to be important for ...

Emergent Patterns in Physics: From Equations to Particles and the Cosmos—Andrei CONSTANTIN
This colloquium examines three examples of emergent patterns in physics. First, we investigate the statistical regularities found in the distribution of mathematical operators within the equations of physics, which point towards an underlying structure governing physical laws. Next, we explore how advanced computational techniques, such as neural networks and genetic ...

Theory precision for collider explorations—Laura REINA
Precision physics has played a crucial role in the history of particle
physics, often providing indirect evidence for particles that have
been later on discovered. Current experiments at the Large Hadron
Collider (LHC) are stress testing the Standard Model and probing new
physics with great precision through a multitude of ...

Counting microstates of black holes—Vijay BALASUBRAMANIAN
On the basis of general relativity and quantum mechanics in curved spacetimes, Bekenstein and Hawking proposed that black holes behave as thermodynamic objects carrying an entropy S = A / 4 G, where A is the area of the event horizon and G is Newton's constant. This remarkable formula is universal ...

Which came first: supermassive black holes or galaxies?—Joe SILK
Insights from JWST observations are shedding new light on the chronology and nature of AGN in the context of early galaxy evolution. I argue that AGN feedback evolved from a short-lived, high redshift phase when relatively dense momentum-conserving central outflows in dusty ultracompact galaxy hosts stimulated vigorous early star formation ...

The role of the chiral anomaly in polarized deeply inelastic scattering: Topological screening, emergent axion-like dynamics and sphaleron transitions in QCD at high energies.—Raju VENUGOPALAN
The contrast between the simplicity of the QCD Lagrangian, and its emergent subtle non-perturbative dynamics, is illustrated for the cross-section for a simple process, the scattering of a polarized virtual photon off a polarized proton. This process is sensitive to the net helicity of quarks in the proton and, as ...
