GARLIC - GAmma Reconstruciton for the LInear Collider
The GARLIC algorithm is based on the REPLIC package. Its main idea is to make use of the typical shape of an electromagnetic shower. Due to its high density, a simple neighbour criterion is sufficient for clustering. In this way, noise hits as well as fluctuations in the extremities of the shower are suppressed and at the same time the two-particle separation is optimised. GARLIC has benn imple...
متن کاملPolarized gamma-ray emission from the crab.
Pulsar systems accelerate particles to immense energies. The detailed functioning of these engines is still poorly understood, but polarization measurements of high-energy radiation may allow us to locate where the particles are accelerated. We have detected polarized gamma rays from the vicinity of the Crab pulsar using data from the spectrometer on the International Gamma-Ray Astrophysics Lab...
متن کاملhep - ph / 0005082 Prospects of Squark & Slepton searches at a Gamma Gamma Collider
We examine the prospects of detecting sfermions at a gamma gamma collider. Once produced, a slepton can decay into a pair of quarks (jets) through R-parity violating interactions. Similarly, a squark may decay into a lepton-quark pair. Analyzing the corresponding Standard Model backgrounds, namely 4-jet and dilepton plus dijet final states respectively, we show that the sfermion can be detected...
متن کاملA Chirped-pulse Regenerative-amplifier Fel for the Gamma-gamma Collider*
During a Workshop on Gamma-Gamma Colliders in Lawrence Berkeley Laboratory, it was pointed out that an 1μm laser that can produce 1-J, 1-ps pulses at a few hundred hertz is required. With high-power scalability and ease of formatting, an FEL can be a promising candidate for such a laser. We propose an FEL scheme based on chirped-pulsed regenerative amplification to achieve this high peak-power ...
متن کاملCrab-crossing in a Tau-charm Facility*
where AQ is the linear tune shift parameter, y = E/moc2 is the Lorentz factor, cZ is the horizontal emittance, f is the bunch collision frequency-which is equal to the number of bunches times circumferential frequency, r, is the classical electron radius, and ,&p is the vertical beta function at the interaction point (IP)..w. To obtain Eq. (1) ‘t 1 is assumed that the coupling factor Ic = cy/c,...
