Effective description of Nelson-Barr models and the theta parameter
Nelson-Barr theories solve the strong CP problem with CP spontaneously broken at Λ_{CP} and transmitted to the CP conserving version of the SM through vector-like quarks (VLQs). For an arbitrary number of CP breaking scalars and VLQs, we perform the full one-loop matching calculations at Λ_{CP} up to dimension five operators and the relevant matching calculations at the VLQ scale relevant to tracking the contributions to the parameter \barθ. In the EFT after the CP breaking scalars have been…

Mountainhead is good TV. An exaggeration of white tech bro culture, a story about an AI apocalypse, made by Jesse Armstrong (of Succession fame). The real surprise is how good Cory Michael Smith is in the lead role.

The presentable stable envelope of an exact category
We prove an analogue of the Gabriel--Quillen embedding theorem for exact $\infty$-categories, giving rise to a presentable version of Klemenc's stable envelope of an exact $\infty$-category. Moreover, we construct a symmetric monoidal structure on the $\infty$-category of small exact $\infty$-categories and discuss the multiplicative properties of the Gabriel--Quillen embedding. For $E$ an Adams-type homotopy associative ring spectrum, this allows us to identify the symmetric monoidal $\infty$-…

Soft theorems of tree-level ${\rm Tr}(ϕ^3)$, YM and NLSM amplitudes from $2$-splits
In this paper, we extend the method proposed in \cite{Arkani-Hamed:2024fyd} for deriving soft theorems of amplitudes, which relies exclusively on factorization properties including conventional factorizations on physical poles, as well as newly discovered $2$-splits on special loci in kinematic space. Using the extended approach, we fully reproduce the leading and sub-leading single-soft theorems for tree-level ${\rm Tr}(ϕ^3)$ and Yang-Mills (YM) amplitudes, along with the leading and sub-lead…

Både mindfulness och känsloreglering ingår också som delar i Idrottshoppet, så det är värt att beakta eventuella risker med dessa metoder.

Calamus 22 Passing stranger!
An absolutely smoldering poem of unfulfilled desire from a casual encounter. It is delicious for its clear and direct explication of a very complicated emotion. The hottest line:
You give me the pleasure of your eyes, face, flesh, as we pass
The poem manages to capture three things in just ten lines.
Whitman is generously pan-gender but the text still feels queer-coded to me. Specifically in how the desire is kept secret: "I am not to speak to you... I am to wait". Combined with the street-cruising scenario (a theme in previous poems) and I can definitely relate to my gay experience.

Fermion Masses and Mixing in String-Inspired Models
We study a class of supersymmetric Froggatt-Nielsen (FN) models with multiple U(1) symmetries and Standard Model (SM) singlets inspired by heterotic string compactifications on Calabi-Yau threefolds. The string-theoretic origin imposes a particular charge pattern on the SM fields and FN singlets, dividing the latter into perturbative and non-perturbative types. Employing systematic and heuristic search strategies, such as genetic algorithms, we identify charge assignments and singlet VEVs that …

This year a lot of corporations are withdrawing Pride sponsorships. Others are still with us but less enthusiastically so.
