Abstract The KAHVE Laboratory, at Boğaziçi University, Istanbul, Turkey is home to an educational proton linac project. beam will originate from a 20 keV H+ source and be delivered two module Radio Frequency Quadrupole (RFQ) operating 800 MHz via low energy transport (LEBT) line. Currently, the design phase being over, commissioning stability tests are ongoing for beamline which already produced installed except RFQ manufactured. This work summarizes design, production test phases of ion...
The pair production of heavy fourth-generation quarks, which are predicted under the hypothesis flavor democracy, is studied using tree-level Monte Carlo generators and fast detector simulation. Two heavy-quark mass values, 500 750$\gev$, considered with assumption that fourth family mixes primarily two light families. It shown a clear signature will be observed in data collected by ATLAS detector, after first year low-luminosity running at Large Hadron Collider.
This summary of the 3rd "Beyond 3 Generation Standard Model" workshop presents following four statements (and their implications) for ongoing and future searches a fourth generation: 1) The enhancement Higgs gluon-gluon production cross-section times branching fraction many search channels studied at Large Hadron Collider (LHC) is not flat factor 9; 2) Electroweak precision data allows only generation, even more generations are allowed; 3) Consideration mixing significantly changes...
We propose a channel for the possible discovery of new charged leptons at Large Hadron Collider. The proposed final state contains three same-sign leptons, making this practically backgroundless. method is illustrated two different cases: 4-family standard model and grand unified theory based on E6 gauge group. An example study taking 250 GeV as lepton mass shows that in both models, about eight signal events can be expected 14 TeV center-of-mass energy with 1 fb−1 integrated luminosity....
Recent improvements to OPUCEM, the tool for calculation of contributions various models oblique parameters, are presented. OPUCEM is used calculate available parameter space four family Standard Model given current electroweak precision data. It shown that even with restrictions on Higgs boson and new quark masses presented in 2011 Autumn conferences, there still enough allow a fourth generation Dirac type neutrinos. For Majorana neutrinos, allowed larger. The data also appear favor non-zero...
We present a simulation-based study for monitoring Akkuyu nuclear power plant's activity using antineutrino flux originating from the reactor core. A gadolinium-doped water Cherenkov detector was designed and optimization studies were performed Geant4 simulation toolkit. It found that bottom (or top) face of target should be instrumented by six 10-inch-diameter photomultiplier tubes with photon detection efficiency about 35% optimum Gd concentration to 0.3%-0.5%. The first on design facility...

The 2nd International Conference on Particle Physics in memoriam Engin Arık and her Colleagues: Fatma Şenel Boydağ, İskender Hikmet, Mustafa Fidan, Berkol Doğan Abat was held at Doğuş University, İstanbul, Turkey 20–25 June 2011. conference organized jointly by the Boğaziçi Universities, with support from CERN Turkish Academy of Sciences.
We correct an unintentional minor error in our recent publication. The correction is the second paragraph of section 3, where we discuss EW oblique parameters computed for fourth generation leptons, and accounts a miscalculation caused by errors references. Figure 3 also corrected, together with its caption. add comments on own implementation formulas references, possible cross-checking future. These corrections do not change any other part paper or conclusions.
While the Higgs model is best studied scenario of electroweak symmetry breaking, a number strongly-coupled models exist, predicting new signatures. Recent studies WW and WZ final states at ATLAS CMS experiments are summarized expected sensitivities presented within frameworks technicolor straw-man chiral Lagrangian.
We study 100 images of early LHC collisions that were recorded by the ATLAS experiment and made public for outreach purposes, extract charged particle multiplicity as a function momentum proton-proton at sqrt(s) = 7 TeV. As we have already been pre-processed Collaboration, tracks are visible, but available to only in form low-resolution bitmaps. employ two separate image processing methods, one based on industry-standard OpenCV library C++, another self-developed algorithms Python. present...
