We discuss a $\ensuremath{\sim}3\ensuremath{\sigma}$ signal (local) in the light Higgs-boson search diphoton decay mode at $\ensuremath{\sim}96\text{ }\text{ }\mathrm{GeV}$ as reported by CMS, together with $\ensuremath{\sim}2\ensuremath{\sigma}$ excess $b\overline{b}$ final state Large Electron Positron Collider (LEP) same mass range. interpret this possible Higgs boson 2 doublet model type II an additional singlet, which can be either complex (2HDMS) or real (N2HDM), where 2HDMS so far has...
Abstract The Two Higgs Doublet model extended with a complex scalar singlet (2HDMS) is well-motivated Beyond Standard Model candidate addressing several open problems of nature. In this work, we focus on the dark matter (DM) phenomenology where real part obtains vacuum expectation value. characterized by an enlarged spectrum comprising six physical bosons and pseudoscalar DM candidate. We address impact accommodating 95 GeV excess 2HDMS parameter space observables after including all...
The Compact Linear Collider (CLIC) is a mature option for the future of high energy physics. It combines benefits clean environment $e^+e^-$ colliders with operation at centre-of-mass energies, allowing to probe scales beyond reach Large Hadron (LHC) many scenarios new This places CLIC project privileged spot in between precision and frontiers, capabilities that will significantly extend knowledge on both fronts end LHC era. In this report we review revisit potential search, directly...
This report summarizes a study of the physics potential CLIC e+e- linear collider operating at centre-of-mass energies from 1 TeV to 5 with luminosity order 10^35 cm^-2 s^-1. First, complex is surveyed, emphasis on aspects related its capabilities, particularly and energy, also possible polarization, \gamma\gamma e-e- collisions. The next Test facility, CTF3, R&D programme are reviewed. We then discuss experimentation CLIC, including backgrounds experimental conditions, present conceptual...
With the discovery of Higgs boson, spectrum particles in Standard Model (SM) is complete. It more important than ever to perform precision measurements and test for deviations from SM predictions electroweak sector. In this report, we investigate two themes arena measurements: observables (EWPOs) that particle content couplings minimal supersymmetric SM, involving multiple gauge bosons final state which provide unique probes basic tenets symmetry breaking. Among EWPOs focus our discussion on...
A bstract Discrete symmetries play an important role in several extensions of the Standard Model (SM) particle physics. For instance, order to avoid flavor changing neutral currents, a discrete Z 2 symmetry is imposed on Two-Higgs-Doublet (2HDM). This can lead formation domain walls (DW) as gets spontaneously broken during electroweak breaking early universe and form between regions whose vacua are related by symmetry. Due this simultaneous spontaneous both symmetry, vacuum manifold consists...
Abstract The two-Higgs-doublet model augmented with a complex scalar singlet (2HDMS) is well-motivated candidate for Beyond Standard Model (BSM) Physics. We investigate the dark matter phenomenology of 2HDMS as candidate. perform study parameter space allowed by existing theoretical and experimental constraints from matter, flavour physics collider searches. Further, we discuss few benchmark scenarios to test discovery potential at HL-LHC future high-energy $$e^+e^-$$ <mml:math...
An experiment (E166) at the Stanford Linear Accelerator Center has demonstrated a scheme in which multi-GeV electron beam passed through helical undulator to generate multi-MeV, circularly polarized photons were then converted thin target produce positrons (and electrons) with longitudinal polarization above 80% 6 MeV.

There are many possibilities for new physics beyond the Standard Model that feature non-standard Higgs sectors. These may introduce sources of CP violation, and there be mixing between multiple bosons or other scalar bosons. Alternatively, a composite state, even no at all. scenarios have important implications collider as well cosmology, understanding their phenomenology is essential full comprehension electroweak symmetry breaking. This report discusses most relevant theories which go its...
