Enabling gender equality by empowering all genders to effectively participate in modern society is one of the most important advances towards sustainable development, encompassing equal representation in the political office, labor market, and civil society (Sustainable Development Goal 5, or SDG5). The goal of this chapter is to improve understanding of gender empowerment issues in the Arctic at the national, regional, and local levels, and to identify concrete strategies for political, economic, and civic gender empowerment, and thereby facilitate sustainable policy making for the Arctic. 

Road infrastructure development is an existing, but not a frequent element of extractive industry benefit-sharing frameworks in remote northern regions. However, it is often at the center of extractive activity and inflicts major impact on environment and communities. This paper examines the benefits and impacts derived from development of informal roads, i.e., vehicular roadways beyond the current publicly-governed road networks constructed, maintained and/or used by various entities and individuals based on private, special purpose and/or informal practices and regulations. Based on several field studies, GIS analysis of road networks and examination of secondary sources, the article investigates the use of informal roads as a form of benefit-sharing and details their impact on mobilities, environment and livelihoods of local and indigenous communities in the Irkutsk Oil and Gas region, Russia. We argue that construction, maintenance and use of the industry-built roads can be a part of benefit-sharing agreements, albeit mostly semi-formal and negotiated. The gains and problems stemming from ‘trickle-down’ (i.e., unintended) effects of the road networks are the most significant. The community-relevant implications of informal roads go far beyond immediate impacts on surrounding environment, but deeply affect subsistence activities, mobility, food security, personal safety and even consumer preferences of the indigenous residents.

While researchers of social-ecological systems acknowledge existence of formal and informal institutions affecting social-ecological governance, the role of informal sector in the land use change remains understudied. Moreover, existing studies of informal land use are focused mostly on urban areas, such as informal settlements. We argue that the remote regions would be another important area for inquiries. Informal, e.g. unobserved by official records, land use changes there are related to high-speed dynamics of resource extraction projects and location mostly in the regions of traditional land use practices of indigenous people. In particular, we focus on informal roads, which in the Arctic and Subarctic remote regions often remain understudied due to their small size, chaotic, temporal or even seasonal nature, private ownership or traditional subsistence functions. Despite their absence on official maps, they have significant social, economic and environmental impact on local, predominantly indigenous, communities. The study area: the north of Irkutsk region and Republic of Buryatia that the last decades has undergone rapid changes of traditional way of life of "old settlers", native Buryats and Evenks, collapse of the Soviet economy, development of oil and gas extractive industries and infrastructure, environmental regulations to protect the Lake Baikal and tourism development. The data was obtained in 2016-2018 at the municipal and local levels using interviews, observations, statistics and cartographic tools. As a result, we identified formal and informal elements of transportation infrastructure with common set of characteristics (e.g. time of development; purpose; present conditions; changes in location; use) and distinguished the specifics of their maintenance requirements, the forms of ownership, seasonality and local traditions. The future plans to use remotely-sensed data, coordinated visual mapping sessions, and field studies for understanding land use changes due to development of informal road networks will be discussed in the presentation. 

A<sc>bstract</sc> A search for beyond-the-standard-model neutral Higgs bosons decaying to a pair of bottom quarks, and produced in association with at least one additional bottom quark, is performed with the CMS detector. The data were recorded in proton-proton collisions at a centre-of-mass energy of 13 TeV at the CERN LHC and correspond to an integrated luminosity of 36.7–126.9 fb⁻¹, depending on the probed mass range. No signal above the standard model background expectation is observed. Upper limits on the production cross section times branching fraction are set for Higgs bosons in the mass range of 125–1800 GeV. The results are interpreted in benchmark scenarios of the minimal supersymmetric standard model, as well as suitable classes of two-Higgs-doublet models. 

A<sc>bstract</sc> The measurements of the Higgs boson (H) production cross sections performed by the CMS Collaboration in the four-lepton (4ℓ, ℓ= e,μ) final state at a center-of-mass energy$$\sqrt{s}$$= 13.6 TeV are presented. These measurements are based on data collected with the CMS detector at the CERN LHC in 2022, corresponding to an integrated luminosity of 34.7 fb⁻¹. Cross sections are measured in a fiducial region closely matching the experimental acceptance, both inclusively and differentially, as a function of the transverse momentum and the absolute value of the rapidity of the four-lepton system. The H → ZZ → 4ℓinclusive fiducial cross section is measured to be$${2.89}_{-0.49}^{+0.53}{\left({\text{stat}}\right)}_{-0.21}^{+0.29}\left({\text{syst}}\right)$$fb, in agreement with the standard model expectation of$${3.09}_{-0.24}^{+0.27}$$fb. 

A measurement of the Higgs boson mass and width via its decay to two $Z$bosons is presented. Proton-proton collision data collected by the CMS experiment, corresponding to an integrated luminosity of $138{\mathrm{fb}}^{-1}$at a center-of-mass energy of 13 TeV, is used. The invariant mass distribution of four leptons in the on-shell Higgs boson decay is used to measure its mass and constrain its width. This yields the most precise single measurement of the Higgs boson mass to date, $125.04\pm 0.12\mathrm{GeV}$, and an upper limit on the width ${\mathrm{\Gamma }}_H<330\mathrm{MeV}$at 95% confidence level. A combination of the on- and off-shell Higgs boson production decaying to four leptons is used to determine the Higgs boson width, assuming that no new virtual particles affect the production, a premise that is tested by adding new heavy particles in the gluon fusion loop model. This result is combined with a previous CMS analysis of the off-shell Higgs boson production with decay to two leptons and two neutrinos, giving a measured Higgs boson width of ${3.0}_{-1.5}^{+2.0}\mathrm{MeV}$, in agreement with the standard model prediction of 4.1 MeV. The strength of the off-shell Higgs boson production is also reported. The scenario of no off-shell Higgs boson production is excluded at a confidence level corresponding to 3.8 standard deviations. © 2025 CERN, for the CMS Collaboration2025CERN 

The Chapter aims to deepen the understanding of gender equality and empowerment issues in the Arctic region at the national, regional, and local levels, and identify concrete strategies for gender political, economic, and civic empowerment, thereby facilitating sustainable policy-making processes for the New Arctic. The Chapter "Empowerment and Fate Control" is a part of the peer-reviewed Pan-Arctic Report "Gender Equality in the Arctic," undertaken under the auspices of the Arctic Council's Sustainable Development Working Group (SDWG) and the Icelandic Chairmanship Programme 2019-2021. 

A<sc>bstract</sc> A search for heavy, long-lived, charged particles with large ionization energy loss within the silicon tracker of the CMS experiment is presented. A data set of proton-proton collisions at a center of mass energy at$$ \sqrt{s} $$ $\sqrt{s}$= 13 TeV, collected in 2017 and 2018 at the CERN LHC, corresponding to an integrated luminosity of 101 fb⁻¹, is used in this analysis. Two different approaches for the search are taken. A new method exploits the independence of the silicon pixel and strips measurements, while the second method improves on previous techniques using ionization to determine a mass selection. No significant excess of events above the background expectation is observed. The results are interpreted in the context of the pair production of supersymmetric particles, namely gluinos, top squarks, and tau sleptons, and of the Drell-Yan pair production of fourth generation (τ′) leptons with an electric charge equal to or twice the absolute value of the electron charge (e). An interpretation of a Z’ boson decaying to twoτ′ leptons with an electric charge equal to 2eis presented for the first time. The 95% confidence upper limits on the production cross section are extracted for each of these hypothetical particles.
