We review the present status of the hadronic light-by-light contribution to muon g - 2 and critically compare recent calculations.

A new fragmentation model for multigluon strings is presented

Lifetimes of some low-lying quartet levels in sulphur, chlorine and iron have been measured using the beam-foil technique. In general, the lifetimes obtained by curve fitting are in agreement with theory. However, the lifetime results for 3s3p(3P)3d 4P04D0 are somewhat higher than predicted, possibly due to the neglection of some of the cascades in the data analysis

Arbetet utreder faderskapspresumtionen och närliggande rättsområden. Syftet med detta är att granska presumtionen och utvärdera om denna är att anse fyll-ler sitt syfte. Detta görs genom att analysera såväl hur det sett ut historiskt som att konstatera hur den gällande rätten ser ut. Detta har även ställts emot de intressen som finns i samhället, hos föräldrarna samt principen om barnets bästa. HThe project audits the presumption of fatherhood in the Swedish legal system and related legal areas. This is done to evaluate if the presumption is fulfilling its purpose. To achieve this a thorough analysis of the subject is conducted. The history of the legal area is explored, and the applicable law is reviewed. The interests in of the different involved parties such as the parents and the publ

We report on preliminary results from time-resolved optical spectroscopy of the He-rich variable white dwarf GD 358.

We highlight some results from our high-resolution spectroscopic elemental abundance survey of F and G dwarf stars in the solar neighbourhood.

Objective: To redesign the current assembly process of the Ektorp Sofa from IKEA in order to improve cycle times, quality levels and to reduce, if possible, costs associated with manufacturing, production times and materials. IKEA wants to increase either the productivity or the quality standard of the Ektorp Sofa by simplifying the processes involved in the construction of the sofa and modernizin

Recent progress on the parton distribution functions of the photon, both real and virtual, is briefly reviewed and experimental possibilities at HERA are discussed.

Exercising your OA-affected joints is really important  Agneta had long struggled with pain in her right knee, but because she felt she could still manage daily life despite the discomfort, it took a while before she sought medical advice. However, delaying seeking care meant postponing the right treatment, which eventually led to an emergency hospital visit. At the hospital, she underwent an X-ra

This master’s thesis project report deals with the design of multiplier for the reference signal to the Phase Locked Loop (PLL) used in WLAN application. The reference multiplier designed is based on a newly proposed architecture of dual loop feedback Delay Locked Loop (DLL) in which multiplication is performed within the loops. To lock the DLL, input signal is required to be delayed only for threKamal Kumar Gupta DLL Based Reference Multiplier for the use in a PLL for WLAN applications In modern wireless communication system, a frequency synthesizer/multiplier is one of the main building blocks of the system. For on-chip application, a frequency synthesizer is used as local oscillator (LO) to generate precise frequency from a single base frequency source, usually a crystal oscillator. Th

Tanken att beskriva världen utifrån dess minsta beståndsdelar har levt ibland oss ända sedan Demokritos leverne. Det dröjde dock drygt 2300 år innan mänskligheten nådde en någorlunda tillfredställande teori för att förklara elementarpartiklarnas egenskaper och interaktioner, den så kallade Standardmodellen. Sedan dess har jakten efter en mer allmängiltig teori pågått. Denna uppsats behandlar en sThe thesis treats the construction of a supersymmetric model, inspired by an E8 unfication scenario. Via the introduction of adjoint representation chiral superfields, in combination with the inclusion of a global generation symmetry, the Standard Model fermion candidates are protected from gaining any mass until electroweak symmetry breaking. In addition, an accidental global baryon symmetry proh

Att föremål har massa är inte någonting vi ifrågasätter i det vardagliga livet. Att förstå \emph{varför} materiens minsta byggstenar, elementarpartiklarna, har massa är däremot inte så enkelt. I standardmodellen, som utgör den fysikaliska beskrivningen för naturens allra minsta beståndsdelar, spelar den så kallade Higgsmekanismen en avgörande roll för att förklara hur elementarpartiklar får massa.In this master thesis we consider some phenomenological aspects of two-Higgs-doublet models, both elementary and composite ones. The emphasis is on calculating and understanding first order phase transitions in such models, constrained to be in agreement with existing collider data on the Higgs sector. We also consider the contribution to the gravitational wave background of the universe that woul

In this contribution I want to discuss three phenomena, where effects of fluctuations are very important, multiplicity distributions, diffractive excitation, and nucleus collisions.

A simple model for the gluon structure function at small x is presented, which gives an intuitive picture of the transition between the DGLAP and BFKL regimes
