Abstract Massless chiral excitations can arise from the interactions between a fermion and an axion string, propagating along the string and allowing it to superconduct. The properties of these excitations, or zero modes, dictate how the string inter

Abstract When the Froggatt-Nielsen mechanism is used to explain the Standard Model flavor hierarchy, new physics couplings are also determined by the horizontal symmetry. However, additional symmetries or dynamics in the UV can sometimes lead to a de

Abstract Anomaly detection relies on designing a score to determine whether a particular event is uncharacteristic of a given background distribution. One way to define a score is to use autoencoders, which rely on the ability to reconstruct certain

Abstract One of the key tasks of any particle collider is measurement. In practice, this is often done by fitting data to a simulation, which depends on many parameters. Sometimes, when the effects of varying different parameters are highly correlate

Abstract A statistically significant excess of gamma rays has been reported and robustly confirmed in the Galactic Center over the past decade. Large local dark matter densities suggest that this Galactic Center Excess (GCE) may be attributable to ne

Abstract Mixing of axion fields is widely used to generate EFTs with phenomenologically advantageous features, such as hierarchies between axion couplings to different gauge fields and/or large effective field ranges. While these features are strongl

In this short paper we present a so far unnoticed syntactic constraint on contrastive focus reduplication (CR), a phenomenon that restricts the semantics of the reduplicated element to a prototypical meaning (but has other uses as well): The CR const

Abstract Modern machine learning techniques, such as convolutional, recurrent and recursive neural networks, have shown promise for jet substructure at the Large Hadron Collider. For example, they have demonstrated effectiveness at boosted top or W b

It has been observed that cross-linguistically the core posture verbs ‘sit’/‘stand/‘lie’ can extend their meaning beyond the literal sense encoding posture or spatial orientation (see Newman 2002 for an overview). In the cognitive literatur

Background: Worldwide, around 21 million children would benefit from palliative care and over 7 million babies and children die each year. Whilst provision of paediatric palliative care is advancing, there major gaps between what should be done, and
