The role of elementary particle accelerators CEPC Linac design C. Rubbia C. Meng, J. Zhang, X. Li, G. Pei, D. Wang, S. Pei, J. Gao and Y. Chi DOI: 10.1142/S0217751X18440104 DOI: 10.1142/S0217751X19400050 The present article gives an overview of the particle The Circular Electron–Positron Collider (CEPC) is a 100-km accelerators from their early evolution to the current stage ring e+e− collider for a Higgs factory. The injector of CEPC of accelerators and colliders. Also discussed are the future is composed of Linac and Booster. The Linac is a normal developments of the LHC and other new machines, as well conducting S-band Linac with a frequency of 2860 MHz; as the alternative Muon Collider. it provides electron and positron beams at an energy of up to 10 GeV with 100 Hz repetition frequency of 100 Hz. The Linac design and dynamic simulation results are discussed in detail in this paper, including electron bunching system, positron source, electron bypass transport line, damping ring and main Linacs.

Performance of the TOTEM Detectors at the Novel laser-plasma TeV electron-positron LHC linear colliders G. Antchev et al. (The TOTEM Collaboration) K. Nakajima, J. Wheeler, G. Mourou and T. Tajima DOI: 10.1142/S0217751X13300469 DOI: 10.1142/S0217751X19430036 TeV center-of-mass energy electron-positron linear colliders comprising seamlessly staged capillary laser-plasma accelerators are presented. A moderate intensity laser pulse coupled with the single electromagnetic hybrid mode in a gas-filled capillary can generate plasma waves in the linear regime, where laser wakefields can accelerate equally focused electron and positron beams. In multiple stage capillary accelerators, a particle beam with respect to the laser wakefield can undergo consecutive acceleration up to TeV energies, associated with continuous transverse focusing in a beam size down to a nanometer level, being capable of a promising electron-positron linear collider with very high luminosities of the order of 1034 cm−2s−1. The transverse and longitudinal beam dynamics of beam particles in plasma wakefields with the effects of radiation reaction and multiple Coulomb scattering are investigated numerically to estimate the luminosities in beam-beam collisions with the effects of beamstrahlung radiation and bunch disruption.

Analysis of an SU(8) model with a spin-1/2 Multiquark states in the ThomasFermi quark field directly coupled to a gauged Rarita- model and on the lattice Schwinger spin-3/2 field W. Wilcox and S. Baral S. L. Adler DOI: 10.1142/S0217751X19410082 DOI: 10.1142/S0217751X19502300 We describe work being done at Baylor University investigating In earlier work we analyzed an abelianized model in which a the possibility of new states of mesonic matter containing two gauged Rarita–Schwinger spin-3/2 field is directly coupled or more quark–antiquark pairs. To put things in context, we to a spin-1/2 field. Here, we extend this analysis to the begin by describing the lattice approach to hadronic physics. gauged SU(8) model for which the abelianized model was a We point out there is a need for a quark model which can simplified substitute. We calculate the gauge anomaly, show give an overall view of the quark interaction landscape. A that anomaly cancellation requires adding an additional left new application of the Thomas–Fermi (TF) statistical quark chiral representation 8ˉ spin-1/2 fermion to the original fermion model is described, similar to a previous application to complement of the SU(8) model, and give options for restoring baryons. The main usefulness of this model will be to detect boson–fermion balance. We conclude with a summary of systematic energy trends in the composition of the various attractive features of the reformulated SU(8) model, including particles. It could be a possible connection to the E root lattice. a key to identifying 8 families of bound states, rather than individual cases.

Unruh acceleration radiation revisited J. S. Ben-Benjamin, M. O. Scully, S. A. Fulling, D. M. Lee, D. N. Page, A. A. Svidzinsky, M. S. Zubairy, M. J. Duff, R. Glauber, W. P. Schleich and W. G. Unruh DOI: 10.1142/S0217751X19410057 When ground-state atoms are accelerated and the field with which they interact is in its normal vacuum state, the atoms detect Unruh radiation. We show that atoms falling into a black hole emit acceleration radiation which, under appropriate initial conditions (Boulware vacuum), has an energy spectrum which looks much like Hawking radiation. This analysis also provides insight into the Einstein principle of equivalence between acceleration and gravity. The Unruh temperature can also be obtained by using the Kubo– Martin–Schwinger (KMS) periodicity of the two-point thermal correlation function, for a system undergoing uniform acceleration; as with much of the material in this paper, this known result is obtained with a twist.
