Capacity and limitations of US wild meat donation programmes

People and Nature, EarlyView.
Abstract Historically, sharing of wild harvests to facilitate food security followed concepts of kin selection and reciprocal altruism. However, cultural shifts have reduced access to foods for some populations in modern times. Cultural altruism through sustainably harvested wild meat donation programmes (WDPs) can reduce food and nutritional ...

Hadronic productions of a Higgs boson in association with two jets at next-to-leading order [PDF]

, 2010
We present the calculation of hadronic production of a Higgs boson in association with two jets at next-to-leading order in perturbation theory. We consider amplitudes in an effective theory in which the Higgs couples to gluons in the limit of a large ...

Upgrade des CMS‐Detektors für die Hochratenphase des LHC: Die Runderneuerung von CMS

Physik in unserer Zeit, EarlyView.
Ab 2030 wird der LHC in der Hochratenphase laufen. Die erheblich gesteigerte Proton‐Proton‐Kollisionsrate erfordert ein grundlegendes Update der beiden großen Detektoren ATLAS und CMS, dessen Runderneuerung hier vorgestellt wird. Zusammenfassung Ab 2030 soll der Large Hadron Collider (LHC) am CERN in der Hochratenphase (High Luminosity, High‐Lumi ...

Little Higgs, Non-standard Higgs, No Higgs and All That

, 2007
We give a brief review of recent developments in non-supersymmetric models for electroweak symmetry breaking, including little Higgs, composite Higgs and Higgsless theories. The new ideas such as extra dimensions, AdS/CFT correspondence, dimension-deconstruction, and collective symmetry breaking provide us new tools to construct new models.

Analogies and differences between the logic behind statistical hypothesis testing and proofs by contradiction: What can we learn from them?

Teaching Statistics, EarlyView.
Abstract Statistical hypothesis testing (SHT) is widely employed across numerous scientific disciplines, and a clear understanding of its underlying logic is essential for the broader scientific community. Here, drawing upon both epistemological and statistical perspectives, we aim to clarify—primarily for educational purposes—the logical relationship ...

N=1 Euler Anomaly from RG-dependent metric-Background

EPJ Web of Conferences, 2017
We consider N = 1supersymmetric gauge theories in the conformal window. By applying a suitable matter superfield- and Weyl-transformation the renormalisation group running of the theory is absorbed into the metric.

Strategies for enhancing sensitivity in lateral flow assays

VIEW, EarlyView.
Lateral flow assays (LFAs) are essential for cost‐effective, rapid point‐of‐care diagnostics. However, conventional colourimetric LFAs often lack the sensitivity required for low‐abundance biomarkers. This review evaluates six enhancement strategies: flow modulation, sample preconcentration, advanced reporters, chemical signal amplification, structural

Tunnelling amplitudes and Hawking radiation from worldline QFT

Journal of High Energy Physics
We compare Hawking radiation in a collapse background with Schwinger pair creation in an electric field. The comparison is driven by the presence of an analogue horizon in the Schwinger case, which causally divides spacetime for classical particles, but ...

2 Higgs or not 2 Higgs

Physics Letters B, 2012
Motivated by recent results from the LHC experiments, we analyze Higgs couplings in two Higgs doublet models with an approximate PQ symmetry. Models of this kind can naturally accommodate sizable modifications to Higgs decay patterns while leaving production at hadron colliders untouched. Near the decoupling limit, we integrate out the heavy doublet to
