Multi-brane cosmology

Journal of High Energy Physics, 2023
5D warped extra dimension models with multiple 3-branes can naturally realize multiple hierarchical mass scales which are ubiquitous in physics beyond the Standard Model.

Boosted dark matter from primordial black holes produced in a first-order phase transition

Journal of High Energy Physics, 2023
During a cosmological first-order phase transition in a dark sector, fermion dark matter particles χ can form macroscopic Fermi balls that collapse to primordial black holes (PBHs) under certain conditions.

Phase transitions and the birth of early universe particle physics [PDF]

, 2023
This paper provides a conceptual history of the development of early universe particle physics in the 1970s, focusing on the development of more sophisticated tools for constructing gauge-theories at finite- temperature.

Searching for heavy leptophilic Z′: from lepton colliders to gravitational waves

Journal of High Energy Physics, 2023
We study the phenomenology of leptophilic Z′ gauge bosons at the future high-energy e + e − and μ + μ − colliders, as well as at the gravitational wave observatories.

Emergence and Reduction Combined in Phase Transitions [PDF]

, 2011
In another paper (Butterfield 2011), one of us argued that emergence and reduction are compatible, and presented four examples illustrating both. The main purpose of this paper is to develop this position for the example of phase transitions.

From terminating to transforming : the role of phase-out in sustainability transitions [PDF]

, 2021
Phase-out is rapidly gaining traction as a central part of practical efforts to address sustainability challenges. However, the way it has been conceived of in policy debates and some academic work is problematic in that it (1) tends to be narrowly ...

Committing to bubbles: finding the critical configuration on the lattice

Journal of High Energy Physics
The nucleation of bubbles in first-order phase transitions is traditionally characterised by the critical bubble: defined as the saddle-point solution of the Euclidean action that separates collapsing from expanding field configurations.

Solid Pseudopapillary Neoplasm of the Pancreas in Children and Adolescents: Expert Recommendations

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Solid pseudopapillary neoplasm of the pancreas (SPN) is a rare low‐grade malignant exocrine pancreatic tumor, mostly discovered during the second decade of life in females, with a very good prognosis, provided microscopically complete surgical excision is achieved.

Infant Embryonal CNS Tumors: Molecular Insights and Treatment Considerations for Contemporary Pediatric Neuro‐Oncology

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Embryonal tumors comprise the majority of malignant central nervous system (CNS) neoplasms diagnosed in children under 3 years of age. Compared with their counterparts in older children, these tumors exhibit distinct molecular biology and a more aggressive clinical phenotype, while their management is complicated by the heightened ...

Bounds on the bubble wall velocity

Journal of High Energy Physics
Determining the bubble wall velocity in first-order phase transitions is a challenging task, requiring the solution of (coupled) equations of motion for the scalar field and Boltzmann equations for the particles in the plasma.
