“…For all scans, before applying the constraints, we allow 0.1 < tan β < 50, |α| < π/2 and 2 −(900 GeV) 2 < m 2 12 < (900 GeV) 2 . All (eigenstate) masses are free in the range [50,1000] GeV, but we have also imposed that the masses of the other neutral scalars are away from the Higgs mass 125.9 GeV by more than 5 GeV. These conditions apply to all scans.…”

We analyse the possibility that, in two Higgs doublet models, one or more of the Higgs couplings to fermions or to gauge bosons change sign, relative to the respective Higgs Standard Model couplings. Possible sign changes in the coupling of a neutral scalar to charged ones are also discussed. These \textit{wrong signs} can have important physical consequences, manifesting themselves in Higgs production via gluon fusion or Higgs decay into two gluons or into two photons. We consider all possible wrong sign scenarios, and also the \textit{symmetric limit}, in all possible Yukawa implementations of the two Higgs doublet model, in two different possibilities: the observed Higgs boson is the lightest CP-even scalar, or the heaviest one. We also analyse thoroughly the impact of the currently available LHC data on such scenarios. With all 8 TeV data analysed, all wrong sign scenarios are allowed in all Yukawa types, even at the 1$\sigma$ level. However, we will show that B-physics constraints are crucial in excluding the possibility of wrong sign scenarios in the case where $\tan \beta$ is below 1. We will also discuss the future prospects for probing the wrong sign scenarios at the next LHC run. Finally we will present a scenario where the alignment limit could be excluded due to non-decoupling in the case where the heavy CP-even Higgs is the one discovered at the LHC.Comment: 20 pages, 15 figure

“…This is the wrong sign limit [3] (see also [42,46,47] for the CP-conserving 2HDM and [48] for the complex 2HDM) and it is imposed only at tree-level. The wrong sign scenarios were first studied in the context of the 2HDM in [49,50].…”

“…Historians define microhistory as 'the intensive historical investigation of a relatively well defined … object, most often a single event, or … a community, a group… even an individual person.' 64 They compare it to 'a cinematographic close-up' 65 that can enable the scientist to view unseen and unexpected things. 66 Microhistory typically reduces the scale of historical research, adopting the microscope rather than the telescope.…”

“…127 In fact, certain microhistories present two narrative threads: the principal thread of historical investigation, and a second story detailing the journey of the historian through the archives, her hypotheses, doubts, and uncertainties. 128 By setting great importance on the literary quality of the text, 129 microhistory appeals both to academics and the public.…”

Perspective and Scale in the Architecture of International Legal History

The history of international law has come of age. Once the domain of specialized scholars and practitioners, it has begun to attract the attention of international lawyers, legal historians, and other interested readers. This certainly constitutes a positive development: international law has a high pedagogical value, as it contributes to 'build peace in the minds of men' and women. In parallel, the histories of international law can provide a better understanding of its past, present, and future trajectories. Moreover, the recent success of certain international legal histories shows that interest in international law and its histories is not the reserve of international lawyers or legal historians only. Rather, international legal histories can attract the interest of the public at large. Recent trends such as the turn to history of international law, the parallel turn to international law of history and the resulting emergence of international legal history as a field of study have encouraged an unprecedented interest in methodological questions in international legal history. Should international legal historians focus on the specific or the general? Should their narration be accessible to the many or should it be academic and addressed to the few? This article contributes to these emerging debates by focusing on the perspective and scale of analysis and investigating whether micro-historical approaches can help international legal historians to bridge the gap between the academic realm and the public, unveil unknown or little known international legal histories, and contribute to the development of the field. This article aims to start a discussion on perspective and scale in international legal history and argues for inclusive and pluralist approaches by drawing out the advantages and potential of microhistory in relation to, and combination with, the prevalent doctrinal, institutional, and diplomatic macro-histories of international law.
