Abstract Research Summary We show that multi‐business firms pursuing technologically related diversification often face a paradox. While such strategies can yield superior financial performance through technological synergies, investors with limited attention tend to undervalue them due to their complexity.

Neutrino Oscillations in the Atmospheric Parameter Region: From the Early Experiments to the Present
The aim of this paper is to provide a historical perspective on the main experimental steps which led to the current picture of neutrino oscillations in the “atmospheric parameter region.” In the 1980s a deficit of atmospheric muon neutrinos was observed with the first generation of underground experiments.

A composite Higgs model with minimal fine-tuning: The large-
We suggest a criterion to minimize the amount of fine-tuning in a composite Higgs model. The paradigm of this type of model is the top-condensate model of Bardeen, Hill and Lindner (BHL). Although "minimally fine-tuned", this model failed to account correctly for the masses of the top quark and the 125~GeV Higgs boson.

Pushpin memoir: Making meaning out of murder
Abstract In 2018, my brother Adam Colquhoun, nicknamed “Stretch,” was killed in a bar in Calgary, Alberta by a man he barely knew. Stretch was the kind of person society finds convenient to discard. His history of theft, illicit drug dealing, mental illness, addiction, and homelessness made his humanity “undesirable.” Nevertheless, lessons Stretch ...

Deciphering the minimum of energy of some walking technicolor models
There are quasiconformal theories, like the minimal and ultraminimal technicolor models, which may break dynamically the gauge symmetry of the standard model and at the same time are compatible with electroweak precision data.

Enduring Connexions: Reflections on fieldwork friendships and the gift
Abstract Drawing on the life writing genres of autoethnography and autotheory, this article reflects on the author's enduring friendships with research participants in El Salvador and Cuba through the seminal anthropological concept of the gift.

Composite dark matter and Higgs
We investigate the possibility that Dark Matter arises as a composite state of a fundamental confining dynamics, together with the Higgs boson. We focus on the minimal SU(4)×SU(4)/SU(4) model which has both a Dark Matter and a Higgs candidates arising as

Telling abortion stories: The life of Florence P. Evans (1913–1935)
Abstract This short article provides a coda to the special forum on ‘Reproductive Rights Beyond Roe’. It merges the history of abortion with what Stéphane Gerson calls ‘personal family history’ to consider how historians should imagine, remember and narrativise histories of abortions within their own families and networks of kin.

We investigate radiatively stable classes of pseudo-Nambu-Goldstone boson (pNGB) potentials for approximate spontaneously broken SO(N + 1) → SO(N). Using both the one-loop effective action and symmetry, it is shown that a Gegenbauer polynomial potential ...

b → sγ and → b in technicolor with scalars [PDF]
We consider the radiative decay b → sγ, and the correction to the Zbb vertex in technicolor models with scalars. In these models, the scalar develops a vacuum expectation value when the technifermions condense, and the ordinary fermions develop masses ...
