Supersymmetric Analysis of Spinning Cosmic String Spacetime Within External fields with Aharonov-Bohm interaction

The supersymmetric analysis of spinning cosmic string spacetime, involving an electron in magnetic fields, has been conducted. We examined the Dirac system within extended special functions known as exceptional orthogonal polynomials. Corresponding Dirac system is transformed to a relativistic system with a nonlinear isotonic oscillator. Furthermore, new potential models that extend the radial oscillator by adding rational terms are expressed in terms of the exceptional orthogonal Laguerre $X_{m}$ polynomial. The necessary analyses of the potential, energy levels, and probability density graphs are introduced for various cosmic string topological defects and Aharonov-Bohm interaction parameters.

A Minimal Fermion-Scalar Preonic Model

A minimal fermion-scalar preonic model containing two fermionic and one scalar preons is proposed. This scheme allows to prevent the occurrence of undesired SM-level particles, namely leptons and quarks with unusual electric charges. Similar to the previous FS models, color-octet leptons and color-sextet quarks, which are expected to have masses much lower than the compositeness scale, are predicted. Observation of these particles could provide first indications of preonic models. FCC (SppC) pp option will give opportunity to probe $m_{q_{6}}$ up to 48 (75) TeV and $m_{l_{8}}$ up to 15 (27) TeV within one year operation at nominal luminosity. FCC/SppC based ep and $μ$p colliders will essentially enlarge covered mass region, namely, $m_{e_{8}}$ up to 23/27 TeV and $m_{μ_{8}}$ up to 68/80 TeV.

Supersymmetric Extension of Preonic Models: General Remarks

We present some general remarks on supersymmetric extensions of fermion-scalar and three-fermion preonic models with an assumption of supersymmetry is realized at preonic level. The motivation and the requirement of this assumption are briefly given. In general, supersymmetric extensions of fermion-scalar (three-fermion) models predict 4 (10) "super" partners for each Standard Model fermion.

FCC Based Lepton-Hadron and Photon-Hadron Colliders: Luminosity and Physics

Construction of future electron-positron colliders (or dedicated electron linac) and muon colliders (or dedicated muon ring) tangential to Future Circular Collider (FCC) will give opportunity to utilize highest energy proton and nucleus beams for lepton-hadron and photon-hadron collisions. Luminosity values of FCC based ep, \mup, eA, \muA, \gammap and \gammaA colliders are estimated. Multi-TeV center of mass energy ep colliders based on the FCC and linear colliders (LC) are considered in detail. Parameters of upgraded versions of the FCC proton beam are determined to optimize luminosity of electron-proton collisions keeping beam-beam effects in mind. Numerical calculations are performed using a currently being developed collision point simulator. It is shown that L_{ep}\sim10^{32}\,cm^{-2}s^{-1} can be achieved with LHeC-like upgrade of the FCC parameters.

SppC based energy frontier lepton-proton colliders: luminosity and physics

In this study, main parameters of Super proton-proton Collider (SppC) based lepton-proton colliders are estimated. For electron beam parameters, highest energy International Linear Collider (ILC) and Plasma Wake Field Accelerator-Linear Collider (PWFA-LC) options are taken into account. For muon beams, 1.5 TeV and 3 TeV center of mass energy Muon Collider parameters are used. In addition, ultimate $μ$p collider which assumes construction of additional 50 TeV muon ring in the SppC tunnel is considered as well. It is shown that $L_{ep}$ $\sim$ $10^{32}$ $cm^{-2}s^{-1}$ can be achieved with moderate upgrade of the SppC proton beam parameters. Physics search potential of proposed lepton-proton colliders is illustrated by considering small Bjorken x region as an example of SM physics and resonant production of color octet leptons as an example of BSM physics.

Color Octet Electron Search Potential of the FCC Based e-p Colliders

Resonant production of color octet electron, e_{8}, at the FCC based ep colliders has been analyzed. It is shown that e-FCC will cover much a wider region of e_{8} masses compared to the LHC. Moreover, with highest electron beam energy, e_{8} search potential of the e-FCC exceeds that of FCC pp collider. If e_{8} is discovered earlier by the FCC pp collider, e-FCC will give opportunity to handle very important additional information. For example, compositeness scale can be probed up to hundreds TeV region.

Possible discovery channel for fourth chiral family up-quark at the LHC

Resonant production of fourth chiral family up quark at the LHC via anomalous interactions have been analyzed. It is shown that search for resonances in W^{+}b final states could lead to discovery of the fourth chiral family and simultaneously determine scale of the new physics, presumabely related to the quark and lepton compositeness. Obtained results emphasize an importance of W-leading jet invariant mass analysis in search for W+jets final states at the LHC, both with and without b-tagging.

Resonant production of leptogluons at the FCC based lepton-hadron colliders

Resonant production of leptogluons at the FCC based ep and \mup colliders have been analyzed. It is shown that e-FCC and μ-FCC will cover much wider region of e_{8} and μ_{8} masses than the LHC. While leptogluons with appropriate masses (if exist) will be discovered earlier by the FCC pp collider, lepton-proton colliders will give opportunity to handle very important additional information. For example, compositeness scale can be probed up to multi-hundred TeV region.
