2 breaking effects in 2-loop RG evolution of 2HDM

We investigate the effects of a ℤ 2 symmetry in the CP-conserving Two-Higgs-Doublet-Model (2HDM); which is often imposed to prevent Flavor-Changing-Neutral-Currents (FCNCs) at tree-level. Specifically, we analyze how a breaking of the ℤ 2 symmetry spreads during renormalization group evolution; employing general 2-loop renormalization group equations that we have derived. Evolving the model fro

Investigations into the BFKL mechanism with a running QCD coupling

We present approximations of varying degree of sophistication to the integral equations for the (gluon) structure functions of a hadron ("the partonic flux factor") in a model valid in the leading log approximation with a running coupling constant. The results are all of the BFKL type, i.e., a power in the Bjorken variable x(B)(-lambda) with the parameter lambda determined from the size alpha(0) o

Diffractive Excitation in DIS and pp Collisions

We have in earlier papers presented an extension of Mueller's dipole cascade model, which includes subleading effects from energy conservation and running coupling as well as colour suppressed effects from pomeron loops via a ``dipole swing''. The model was applied to describe the total cross sections in pp and gamma*p collisions. In this paper we present a number of improvements of the model, in

Avoiding reinventing the wheel

En föränderlig omvärld ställer ständigt nya krav på organisationer; utveckling och anpassning är ständigt pågående processer. Framgångsrika idéer har blivit en handelsvara som recept på framgång. I dag har dessutom ett större antal av dagens medarbetare kapacitet att ta till sig de idéer som florerar och kommunikationsforskningen har inte riktigt hunnit med i denna aspekt. Denna uppsats är en kval

Search for technipions in exclusive production of diphotons with large invariant masses at the LHC

We focus on exclusive production of neutral technipion (pi) over tilde (0) in pp collisions at the LHC, i.e. on pp -> pp (pi) over tilde (0) reaction. The dependence of the cross section on parameters of recently proposed vector-like Technicolor model is studied. Characteristic features of the differential distributions are discussed. For not too large technipion masses the diphoton decay channel

Tackling the Uncertainties of Event Generators

This thesis is composed of four papers, which concern Monte Carlo event generators for high energy particle physics. Precise predictions of the outcome of particle collisions are important for the exploration of the Standard Model of particle physics at collider experiments like the LHC at CERN. The papers address the uncertainties of these predictions in different contexts.Paper I presents an alg

Lunds Geotermisystem, en utvärdering av 30 års drift

Kraftringens geotermianläggning i Lund har varit i drift sen 1984. Det är den enda stora geoter-miska anläggningen i Sverige. Efter mer än 30 års drift är det dags att utvärdera hur det har fungerat. Arbetet be-skriver de geologiska förutsättningarna som stratigrafi (formation), formationstemperatur, typ av akvifer, porositet, permeabilitet och vattenkemi, samt driftdata, systemuppbyggnad, funktio

Phenomenology of a Three Higgs Doublet Model with a U(1)xZ2 flavour symmetry

We have studied the main features and the phenomenological consistency of a family-nonuniversal Three Higgs Doublet Model (3HDM) with a softly broken U(1)xZ2 family symmetry that enforces the flavour hierarchies in the Standard Model (SM) while implementing a tree-level Flavour Changing Neutral Current (FCNC) suppression in a Branco-Grimus-Lavoura way. Furthermore, the alignment limit is imposed i

Physical Modeling of Protein Folding

Popular Abstract in Swedish Sekvensbaserade proteinveckningsmodeller utvecklas och testas på peptider med både betablad- och alfahelix-struktur, samt på små helix-proteiner. Modellernas potentialer är minimalistiska och baseras huvudsakligen på vätebindningar och effektiva hydrofobicitetskrafter. Den geometriska representationen av proteinkedjan är däremot detaljerad. Vi studerar det termodynamiskSequence-based models for protein folding are developed and tested on peptides with both alpha- and beta-structure, and on small three-helix-bundle proteins. The interaction potentials of the models are minimalistic and based mainly on hydrogen bonding and effective hydrophobicity forces. By contrast, the geometric representation of the protein chain is detailed. We explore the thermodynamic behav

Inventering av föroreningar vid en brandövningsplats i Linköpings kommun

En inventering har genomförts av perfluorerade ämnen som misstänkts ha släppts ut på en brandövningsplats i Lambohov, Linköpings kommun. Inventeringen har genomförts i samarbete med miljökontoret på Linköpings kommun. Målet var att klargöra om denna brandövningsplats utgör en fara för människor och miljö med störst vikt vid den kemiska föroreningen PFOS, perfluoroktansulfonat. PFOS användes under

Makedoniens rätt att bestämma sitt namn - En kritisk granskning av statssuveräniteten

En suverän stat har en inneboende rättighet att bestämma sitt konstitutionella namn. På grund av namnkonflikten med Grekland har denna rättighet inskränkts för Makedonien. Greklands krav på ett namnbyte har ingen rättslig grund, men som medlem i internationella organisationer har landet haft ett övertag i namnkonflikten och en maktposition. Det ledde till att EG inte erkände Makedonien som en suve

Vad hotar Sverige?

During the last decades Sweden’s security and defence policy has gone through many great changes. The official direction was, up until 2009, neutrality. This was then changed to solidarity in conjunction with the enactment by the Swedish government of the Solidarity Clause of the Treaty of Lisbon in the Swedish defence proposal. The change can be supposed to have affected other defence bodies, for
