of z > 2 Swift gamma - ray bursts
Context. Before the launch of the Swift satellite, the majority of the gamma-ray burst (GRB) afterglows for which Lyα was redshifted into the observable spectrum showed evidence for a damped Lyα absorber. This small sample indicated that GRBs explode either in galaxies, or regions within them, having high neutral hydrogen column densities. Aims. To increase the spectroscopic sample of GRBs with...
متن کاملGARLIC - 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 کاملGamma - Gamma , Gamma - Electron Colliders ∗
It is very likely that in 3-4 years the construction of one or two linear colliders with c.m.s energy up to 0.5–1.5 TeV will be started. Besides eecollisions, linear colliders give a unique possibility to study γγ and γe interactions at energies and luminosities comparable to those in ee collisions. High energy photons for γγ and γe collisions can be obtained using laser backscattering. These t...
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 ...
