Search for fractionally charged particles in proton-proton collisions at = 13 TeV
No full textInternational audienceA search is presented for fractionally charged particles with charge below 1, using their small energy loss in the tracking detector as a key variable to observe a signal. The analyzed data set corresponds to an integrated luminosity of 138 fb of proton-proton collisions collected at = 13 TeV in 2016-2018 at the CERN LHC. This is the first search at the LHC for new particles with charges between 3 and . Masses up to 640 GeV and charges as low as 3 are excluded at 95% confidence level. These are the most stringent limits to date for the considered Drell-Yan-like production mode
Measurement of the double-differential inclusive jet cross section in proton-proton collisions at = 5.02 TeV
No full textInternational audienceThe inclusive jet cross section is measured as a function of jet transverse momentum and rapidity . The measurement is performed using proton-proton collision data at = 5.02 TeV, recorded by the CMS experiment at the LHC, corresponding to an integrated luminosity of 27.4 pb. The jets are reconstructed with the anti- algorithm using a distance parameter of = 0.4, within the rapidity interval 2, and across the kinematic range 0.06 1 TeV. The jet cross section is unfolded from detector to particle level using the determined jet response and resolution. The results are compared to predictions of perturbative quantum chromodynamics, calculated at both next-to-leading order and next-to-next-to-leading order. The predictions are corrected for nonperturbative effects, and presented for a variety of parton distribution functions and choices of the renormalization/factorization scales and the strong coupling
Polygraphs: From Rewriting to Higher Categories
No full textInternational audiencePolygraphs are a higher-dimensional generalization of the notion of directed graph. Based on those as unifying concept, this monograph on polygraphs revisits the theory of rewriting in the context of strict higher categories, adopting the abstract point of view offered by homotopical algebra. The first half explores the theory of polygraphs in low dimensions and its applications to the computation of the coherence of algebraic structures. It is meant to be progressive, with little requirements on the background of the reader, apart from basic category theory, and is illustrated with algorithmic computations on algebraic structures. The second half introduces and studies the general notion of n-polygraph, dealing with the homotopy theory of those. It constructs the folk model structure on the category of strict higher categories and exhibits polygraphs as cofibrant objects. This allows extending to higher dimensional structures the coherence results developed in the first half
Exploring continual learning strategies in artificial neural networks through graph-based analysis of connectivity: insights from a brain-inspired perspective
No full textInternational audienceArtificial Neural Networks (ANNs) aim at mimicking information processing in biological networks. In cognitive neuroscience, graph modeling is a powerful framework widely used to study brain structural and functional connectivity. Yet, the extension of graph modeling to ANNs has been poorly explored especially in term of functional connectivity (i.e. the contextual change of the activity's units in networks). From the perspective of designing more robust and interpretable ANNs, we study how a brain-inspired graph-based approach can be extended and used to investigate their properties and behaviors. We focus our study on different continual learning strategies inspired by the human brain and modeled with ANNs. We show that graph modeling offers a simple and elegant framework to deeply investigate ANNs, compare their performances and explore deleterious behaviors such as catastrophic forgetting
Efficient -isogenies on fast Kummer surfaces
No full textInternational audienceWe give an alternative derivation of -isogenies between fast Kummer surfaces which complements existing works based on the theory oftheta functions. We use this framework to produce explicit formulae for the case of , and show that the resulting algorithms are more efficient than all prior -isogeny algorithms
Observation of exotic resonances in diffractive processes in proton-proton collisions
No full textInternational audienceThe first study of production in diffractive processes in proton-proton collisions is presented. The study is based on an LHCb dataset recorded at centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 5 fb. The data disfavour a nonresonant production but are consistent with a resonant model including several resonant states observed previously only in decays. The state is observed with a significance over and the is confirmed with a significance of more than
Backward DVCS on the pion in Sullivan processes
No full textProceedings for 31st International Workshop on Deep Inelastic ScatteringInternational audienceThe purpose of this work is to do a systematic feasibility study of measuring in backward region deeply virtual Compton scattering on the pion in Sullivan processes in the framework of collinear QCD factorization where pion to photon transition distribution amplitudes (TDAs) describe the photon content of the meson. Our approach employs TDAs based on the overlap of light front wave functions, using a previously developed pion light-front wave function and deriving a consistent model for the light front wave functions of the photon. This work is expected to lead us to an estimate of the cross-sections that could be measured in the future U.S. and China's electron-ion colliders. It will also provide a comparison with the forward Sullivan DVCS case, which gives access to pion GPDs and for which a strong signal is expected
Kwale County Annual Development Plan 2025/2026
No full textThe budget making process of a county government starts with the preparation of a development
plan which should be formulated in accordance with the Constitution. In section 104 of the County Governments Act (CGA) 2012, it is mandatory for a county government to plan and that no public funds shall be appropriated outside a planning framework. Further, section 126 of the Public Finance Management Act, 2012 requires county governments to prepare a development plan in accordance with Article 220 (2) of the Constitution, which should be submitted for approval to the county assembly not later than 1st September of each year. The County Annual Development Plan (CADP) provides the basis for implementing the County Integrated Development Plan (CIDP) and guiding resource allocation to priority projects and programmes. The CADP provides a platform for linking county development priorities in the CIDP to the county annual budget. Section 105 of the County Governments Act 2012 requires the county planning unit to ensure there are linkages between county plans and the national planning framework. The CADP will therefore provide a means for linking the county development priorities to the Kenya Vision 2030 and its MTP IV and also the Kenya Kwanza’s Bottom Up Economic Transformation Agenda (BETA). The CADP will also be linked to the County Performance Management Framework to give evidence based results. The CADP has a Monitoring and Evaluation framework which assessing progress of county programmes and projects thus enabling counties to demonstrate their development results
Kwale County Fiscal Strategy Paper 2025
No full textThis 2025 County Fiscal Strategy Paper(CFSP),which is the third to prepared under the new Achani-Chirema administration, consolidates the progress and gains achieved in the last two years in the implementation of priority programmes and projects articulated in the county socio – economic transformation agenda anchored on the third County Integrated Development Plan (CIDP III) 2023-2027.The five year term plan is linked to the National Government’s Bottom – Up Economic Transformation Agenda(BETA) which is being implemented by the Fourth Medium Term Plan (MTP IV) of the Vision 2030.Consistent with the initiatives of BETA, the County Government of Kwale has given special focus on: improving the citizens’ well-being through continued investment in health; agricultural transformation; youth and women empowerment; infrastructural development (roads and water); and education. The 2025 CFSP has been prepared against a backdrop of stable global and domestic economic outlook. Global economic growth is projected at 3.2 percent in 2024 and 3.3 percent in 2025 from 3.3 percent in 2023. The outlook reflects economic recovery in China, Euro area and UK, despite a slowdown in activity in the USA and Japan. The Kenya economy has remained resilient despite the challenging domestic and external environment. The National Government implemented structural reforms and interventions under the BETA which have stabilized the economy and supported economic recovery from the growth of 4.9 percent in 2022 to 5.6 percent in 2023.
However due to the decline in economic activities and slowdown in private sector credit in the first three quarters of 2024, economic growth dropped to 4.6 percent in 2024. Going forward, economic growth is expected to pick up to 5.3 percent in 2025 and it will be retained over the medium term courteous of the ongoing implementation of the BETA priorities, increased agricultural productivity and resilience in the services sector
