In the days of Copernicus, the most prestigious activities at the Krakow Academy were studies of alchemy and astrology. Since that time a number of scientific revolutions, Copernican and otherwise, have advanced us to a more sophisticated view of the universe based on particle physics and astrophysics. A Standard Model (SM) has emerged with a precise comprehensive description of the constituent...

The research project RD24 [11] is studying applications of the Scalable Coherent Interface (IEEE-1596) standard for the large hadron collider (LHC). First SCI node chips from Dolphin were used to demonstrate the use and functioning of SCI’s packet protocols and to measure data rates. We present results from a first, two-node SCI ringlet at CERN, based on a R3000 RISC processor node and DMA node...

The data acquisition system for the CMS experiment at the large hadron collider (LHC) will require a large and high performance event building network. Several switch technologies are currently being evaluated in order to compare different architectures for the event builder. One candidate is Myrinet. This paper describes the demonstrator which has been setup to study a small-scale (8x8) event ...

In the context of the little Higgs models, we discuss single production of the new charged gauge bosons in association with top quark at the CERN Large Hadron Collider(LHC). We find that the new charged gauge bosons W H and X , which are predicted by the littlest Higgs model and the SU(3) simple model, respectively, can be abundantly produced at the LHC. However, since the main backgrounds comi...

A study of Underlying Events (UE) and Minimum Bias (MB) at Large Hadron Collider (LHC) with CMS and ATLAS detector under nominal conditions is discussed. Using charged particle and charged particle jets, it will be possible to discriminate between various QCD models with different multiple parton interaction schemes, which correctly reproduce Tevatron data but give different predictions when ex...

The O(α) radiative corrections to the process p p (−) → γ∗, Z → `+`− (` = e, μ) are calculated. Factorizing the collinear singularity associated with initial state photon bremsstrahlung into the parton distribution functions, we find that initial state corrections have a much smaller effect than final state radiative corrections. Due to mass singular logarithmic terms associated with photons em...

We investigate the corrections of the littlest Higgs(LH) model and the SU(3) simple group model to single top production at the CERN Large Hardon Collider(LHC). We find that the new gauge bosons W H predicted by the LH model can generate significant contributions to single top production via the s-channel process. The correction terms for the tree-level Wqq couplings coming from the SU(3) simpl...

It is well known that finding and measuring the masses of particles in the Minimal Supersymmetric Standard Model (MSSM) at the Large Hadron Collider (LHC) may be possible using invariant mass distributions in exclusive channels containing nj jets and nl leptons. We perform this analysis for the (nj, nl) = (0, 4) decay of heavy Higgs bosons to neutralinos, pp → H/A → χ̃i χ̃j (i, j = 2, 3, 4), whic...

We studied energy distribution of electrons emitted from samples of the real Cu surface used in the Large Hadron Collider (LHC). The spectra have been detected as a function of scrubbing conditions and have been analyzed by dividing the whole energy range into three energy regions, conventionally termed reflected, rediffused and true-secondary electrons. We observe, for fixed electron impact en...

BACKGROUND Large-scale sequencing projects have now become routine lab practice and this has led to the development of a new generation of tools involving function prediction methods, bringing the latter back to the fore. The advent of Gene Ontology, with its structured vocabulary and paradigm, has provided computational biologists with an appropriate means for this task. METHODOLOGY We prese...
