The non-Abelian Landau-Pomeranschuk-Migdal (LPM) effect arises from the quantum interference between spatially separated, inelastic radiation processes in matter. A consistent probabilistic implementation of this LPM effect is a prerequisite for extending the use of Monte Carlo (MC) event generators to the simulation of jetlike multiparticle final states in nuclear collisions. Here, we propose a l

Under tusentals år trodde människan att detta var Universums mittpunkt. Tack vare vår nyfikenhet, fantasi och lust att upptäcka, vet vi nu att planeter som vår Jord inte är särskilt ovanliga i kosmos. Solen är bara en vanlig stjärna bland hundratals miljoner andra i vår galax, Vintergatan.Med hjälp av världens mest kraftfulla teleskop kan vi utforska mer och mer av Universum. Det vi hittills har uFor thousands of years, mankind thought that this was the centre of the Universe. Thanks to our curiosity, imagination and urge to explore, we now know that planets like our Earth are nothing special in the cosmos. The Sun is just one ordinary star among hundreds of billions in our galaxy, the Milky Way.With the world’s most powerful telescopes, we are able to explore more and more of the Universe

Response to Sheila Twinn commentary on Bramhagen AC. Axelsson I. and Hallström I. Mother’s experiences of feeding situations. An interview study.

Vi dyker tillsammans ner i tropiska hav och observerar tusentals färgglada fiskar simma förbi oss. Vi reser runt Jorden och undersöker olika typer av korallrev och de djur som där bor. Vi lär oss hur forskare tar fram nya metoder för att skydda och hjälpa Korallrevens Värld överleva nu när havstemperaturen stiger.Under vår resa upptäcker vi hur koraller lever, andas samt hur de förökar sig. KorallDive into a tropical ocean and see thousands of colorful fish flutter by. Travel the globe to explore coral reefs teeming with life and learn how scientists are racing to develop sustainable solutions to protect these vitally important ecosystems for the future. Along the way, discover how corals live, breathe, and reproduce, supporting a quarter of all marine life on Earth and providing critical

The successful operation of the Large Hadron Collider (LHC) and the excellent performance of the ATLAS, CMS, LHCb and ALICE detectors in Run-1 and Run-2 with pp collisions at center-of-mass energies of 7, 8 and 13 TeV as well as the giant leap in precision calculations and modeling of fundamental interactions at hadron colliders have allowed an extraordinary breadth of physics studies including pr

Följ med nallebjörnen Ted, och hans blomma, på ett äventyr i solsystemet. Tillsammans utforskar vi förhållanden på olika planeter, och upptäcker var bästa förhållandena finns för Ted att plantera sin blomma. Vi besöker Solen, Merkurius, Venus, dvärgplaneten Pluto, Mars Jorden och Månen. Vi flyger även förbi gasjättarna i vårt solsystem: Jupiter, Saturnus, Uranus och Neptunus.Detta är en interaktivJoin the teddy bear Ted, and his companion Plant, on an adventure around the Solar System investing different places and how they affect us. Together we can learn about Mercury, Venus, the Earth and its Moon, Mars, the dwarf planet Pluto and the giant planets in the outer Solar System: Jupiter, Saturn, Uranus and Neptune.This is an interactive show. The children are encouraged to sing along with t

The discovery of the Higgs boson in 2012, by the ATLAS and CMS experiments, was a success achieved with only a percent of the entire dataset foreseen for the LHC. It opened a landscape of possibilities in the study of Higgs boson properties, Electroweak Symmetry breaking and the Standard Model in general, as well as new avenues in probing new physics beyond the Standard Model. Six years after the

Single top-quark production through the exchange of a t-channel W-boson is the main electroweak production mode for top quarks at the Large Hadron Collider. I discuss a recent development in the theoretical predictions for this process, in which t-channel single-top with an additional jet is combined, at NLO accuracy, with t-channel single top production, without the introduction of a merging scal

Body-mass index (BMI) has increased steadily in most countries in parallel with a rise in the proportion of the population who live in cities 1,2 . This has led to a widely reported view that urbanization is one of the most important drivers of the global rise in obesity 3–6 . Here we use 2,009 population-based studies, with measurements of height and weight in more than 112 million adults, to re

Background: It is unclear whether there are causal associations between blood lipids, statin use and cancer risks. Under certain assumptions, Mendelian randomization analysis of a genetic marker for an exposure eliminates reverse causation and confounding. Methods: We applied Mendelian randomization analysis to genetic scores, comprising 26–41 single-nucleotide polymorphisms (SNPs), as instrumenta

Diffusion MRI yields parameters sensitive to brain tissue microstructure. A structurally important aspect of this microstructure is the myelin wrapping around the axons. This study investigated the forward problem concerning whether water exchange via the spiraling structure of the myelin can meaningfully contribute to the signal in dMRI. Monte Carlo simulations were performed of a system with int

This Report summarizes the results of the activities of the LHC Higgs Cross Section Working Group in the period 2014-2016. The main goal of the working group was to present the state-of-the-art of Higgs physics at the LHC, integrating all new results that have appeared in the last few years. The first part compiles the most up-to-date predictions of Higgs boson production cross sections and decay
