Contact interactions and top-philic scalar dark matter

Journal of High Energy Physics, 2021
We investigate the phenomenology of a scalar top-philic dark matter candidate when adding a dimension-five contact interaction term, as motivated by possible underlying extensions of the Standard Model such as composite Higgs models.

Material Composition Gradient Controls the Autonomous Opening of Banksia Seed Pods in Fire‐Prone Habitats

Advanced Functional Materials, EarlyView.
The seed pod valves of Australian Banksia attenuata plants are not simply bi‐layers which bend when dry. These experiments and models reveal complex mechanics, which allow seed release only after several steps of seed pod opening. Stiffness gradients prevent delamination of the valves during loading, and a shape‐memory function protects the seeds ...

Leptophilic bosons and muon g-2 at lepton colliders

Journal of High Energy Physics, 2021
A light leptophilic boson (scalar or pseudoscalar) has been postulated to explain the muon g-2 anomaly and could be a portal to dark matter. Realizing the leptophilic nature of a singlet boson in the framework of the two-Higgs-doublet-Model of type-X, we

Scaling‐Up of Structural Superlubricity: Challenges and Opportunities

Advanced Functional Materials, EarlyView.
At increasing length‐scales, structural superlubricity (SSL) faces challenges from physical and chemical energy dissipation pathways. This study reviews recent experimental and theoretical progress on these challenges facing the scaling‐up of SSL, as well as perspectives on future directions for realizing and manipulating macroscale superlubricity ...

Higgs Quark Flavor Violation: Simplified Models and Status of General Two-Higgs-Doublet Model

Journal of High Energy Physics, 2020
We study quark flavor violating interactions mediated by the Higgs boson h. We consider observables involving a third generation quark, of both the up and the down quark sectors, like h → bs and t → ch.

Nano‐Topography Enhanced Topological‐Cell‐Analysis in Radiation‐Therapy

Advanced Healthcare Materials, EarlyView.
Radiotherapy, a treatment that implies exposition of cells to radiation, offers promise to treat cancer. Here, it is hypothesized that the nanoscale details of a scaffold can amplify the response of cells to radiation, measured through topological variables, providing ways to assess the efficacy of Radiotherapy treatment.

Comparison of mechanistic and hybrid modeling approaches for characterization of a CHO cultivation process: Requirements, pitfalls and solution paths

Biotechnology Journal, Volume 18, Issue 1, January 2023., 2023
Graphical Abstract and Lay Summary Successful bioprocess modeling starts with experimental planning and accordingly can fail at this early stage. Based on an antibody‐producing CHO fed‐batch process, requirements and pitfalls were investigated, exemplifying their impact on model performance and process characterization.

On the importance of electroweak corrections for B anomalies

Journal of High Energy Physics, 2017
The growing experimental indication of Lepton Flavour Universality Violation (LFUV) both in charged- and neutral-current semileptonic B-decays, has triggered many theoretical interpretations of such non-standard phenomena.

Evaluating the Local Bandgap Across inxGa1‐xas Multiple Quantum Wells in a Metamorphic Laser via Low‐Loss EELS

Advanced Materials Interfaces, EarlyView.
This research explores local bandgap, composition, and strain variations across InxGa₁−xAs quantum wells within a metamorphic laser structure using high‐resolution scanning transmission electron microscopy (STEM) and low‐loss electron energy loss spectroscopy (EELS). Results reveal significant inhomogeneities, particularly near interfaces, with bandgap

Hadron collider probes of the quartic couplings of gluons to the photon and Z boson

Journal of High Energy Physics, 2022
We explore the experimental sensitivities of measuring the gg → Zγ process at the LHC to the dimension-8 quartic couplings of gluon pairs to the Z boson and photon, in addition to comparing them with the analogous sensitivities in the gg → γγ process ...
