A bstract In this work, we present a comprehensive review of the most up-to-date exclusion limits on Vector-Like Quarks (VLQs) derived from ATLAS and CMS data at Large Hadron Collider (LHC). Our analysis encompasses both pair single production modes, systematically comparing results two collaborations to identify employ stringent bounds each mass point. We evaluate excluded parameter space for VLQs under singlet, doublet, triplet representations. For top-like ( T ), rule out masses up 1.49...

In this paper we analyze the process ${B}_{s}\ensuremath{\rightarrow}{l}^{+}{l}^{\ensuremath{-}}$ in a type-II two-Higgs-doublet model (2HDM) and minimal supersymmetric standard (MSSM). All leading terms of Wilson coefficients relevant to are given large $\mathrm{tan}\ensuremath{\beta}$ limit. It is shown that decay width for depends on all parameters except ${m}_{{A}^{0}}$ 2HDM. The branching ratio ${B}_{s}\ensuremath{\rightarrow}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}$...
This report summarises the physics opportunities for study of Higgs bosons and dynamics electroweak symmetry breaking at 100 TeV pp collider.
It is shown that in supersymmetric models the large contributions to $\stackrel{\ensuremath{\rightarrow}}{B}{X}_{s}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}$ come from Feynman diagrams which consist of exchanging neutral Higgs boson loops and are proportional ${m}_{b}{m}_{\ensuremath{\mu}}{\mathrm{tan}}^{3}\ensuremath{\beta}{/m}_{h}^{2}$ when tan \ensuremath{\beta} mass lightest ${m}_{h}$ not too (say, less than 150 GeV). Numerical results show branching ratios can be...
The dominance of the $h\ensuremath{\rightarrow}\ensuremath{\eta}\ensuremath{\eta}$ decay mode for intermediate-mass Higgs boson is highly motivated to solve little hierarchy problem and ease tension with precision data. However, discovery modes ${m}_{h}\ensuremath{\lesssim}150\text{ }\text{ }\mathrm{GeV}$, $h\ensuremath{\rightarrow}\ensuremath{\gamma}\ensuremath{\gamma}$,...
We stude the \textit{holographic} QCD model which contains a quadratic term $ -\sigma z^2$ and logarithmic $-c_0\log[(z_{IR}-z)/z_{IR}]$ with an explicit infrared cut-off $z_{IR}$ in deformed ${\rm AdS}_5$ warp factor. investigate heavy quark potential for three cases, i.e, only correction, both corrections correction. solve dilaton field dilation from Einstein equation, corresponding beta function G{\"u}rsoy -Kiritsis-Nitti (GKN) framework. Our studies show that case negative $\sigma$ or...
In this work, we study the light stop pair signals at LHC. We explore supersymmetry parameter space with nonuniversal gaugino and third-generation masses grand unified theory scale. Recent LHC search results based on $35\text{ }\text{ }{\mathrm{pb}}^{\ensuremath{-}1}$ $1\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of data are implemented to put limits events. The dark matter relic density direct detection constraints also taken into account. Detailed simulations background for some benchmark...
The quartic self-coupling of the Standard Model Higgs boson can only be measured by observing triple-Higgs production process, but it is challenging for Large Hadron Collider (LHC) Run 2 or International Linear (ILC) at a few TeV because its extremely small rate. In this paper, we present detailed Monte Carlo simulation study through gluon fusion 100 hadron collider and explore feasibility mode. We focus on decay channel $HHH\rightarrow b\bar{b}b\bar{b}\gamma\gamma$, investigating detector...
The invariant mass spectrum, forward-backward asymmetry, and lepton polarizations of the exclusive processes $B\to K(K^*)\ell^+ \ell^-, \ell=\mu, \tau$ are analyzed under supersymmetric context. Special attention is paid to effects neutral Higgs bosons (NHBs). Our analysis shows that branching ratio process $\bkm$ can be quite largely modified by asymmetry would not vanish. For $\bksm$, transverse polarization sensitive NHBs, while longitudinal not. both $\bkt$ $\bkst$, NHBs significant....
Feynman loop integrals are a key ingredient for the calculation of higher order radiation effects, and responsible reliable accurate theoretical prediction. We improve efficiency numerical integration in sector decomposition by implementing quasi-Monte Carlo method associated with CUDA/GPU technique. For demonstration we present results several up to two loops both Euclidean physical kinematic regions comparison those obtained from FIESTA3. It is shown that planar non-planar two-loop master...
We perform a detailed hadron-level study on the sensitivity of Higgs boson pair production via $W{W}^{*}W{W}^{*}$ channel with final state $3\ensuremath{\ell}2j+\overline{)E}$ at LHC collision energy $\sqrt{S}=14\text{ }\text{ }\mathrm{TeV}$ and future 100 TeV collider. To avoid huge background from $pp\ensuremath{\rightarrow}ZW+\text{jet}$ processes, we confine to consider four-lepton patterns:...
Abstract pH is a key factor affecting water quality. Traditional detection methods are mostly manually operated, with large workload, low efficiency, and accuracy. In order to improve the efficiency convenience of quality detection, we have designed portable value detector based on NB-IoT(Narrow Band Internet Things) by combining single chip microcomputer wireless transmission technology. It uses STM8L152 microcontroller as core adopts composite electrode measure samples, which...
In this work, we study the light stop pair signals at large hadron collider (LHC) in three coannihilation scenarios. order to yield desired dark matter (DM) relic density, neutralino can coannihilate with stop, chargino and stau, respectively. Signatures of first scenario be probed LHC via associated jet production processes $pp \to j + {\tilde t} t}^*$ by tagging an energetic mono-jet a missing transverse energy. The signatures other two scenarios searched process b-jets final states We...
Higgs pair production is crucial for measuring the boson self-coupling. The dominant channel at hadron colliders gluon fusion via heavy-quark loops. We present results of a fully exclusive simulation based on matrix elements $hh+0$, 1 partons including full loop dependence, matched to parton shower. examine and validate this new description by comparing it with (a) effective theory predictions, (b) exact $hh+0$-parton sample showered Pythia, (c) $hh+1$-parton distributions, looking most...
We explore the potential for discovery of triple-Higgs signal in $2b2l^{\pm}4j+E\!\!\!/$ decay channel at a $100$ TeV hadron collider. consider both Standard Model and generic new-physics contributions, described by an effective Lagrangian that includes higher-dimensional operators. The selected subset operators is motivated composite-Higgs Higgs-inflation models. In Model, we perform parton-level detector-level analysis. Although results are encouraging, demonstrate this mode will be really...
A bstract The left-right symmetric model (LRSM) is a well-motivated framework to restore parity and implement seesaw mechanisms for the tiny neutrino masses at or above TeV-scale, has very rich phenomenology both high-energy high-precision frontiers. In this paper we examine phase transition resultant gravitational waves (GWs) in minimal version of LRSM. Taking into account all theoretical experimental constraints on LRSM, identify parameter regions with strong first-order detectable GWs...
The natural supersymmetry (SUSY) requires that stop, sbottom, and gluino be around one TeV or lighter. By using the direct SUSY search bounds from both ATLAS CMS Collaborations, we examine constraints on in Next to Minimal Supersymmetric Standard Model (NMSSM). We consider two cases of interpretations for Higgs boson data: (1) (SM) like is lightest CP-even boson; (2) SM second boson. find searches at LHC impose a strong constraint light scenarios, can not lighter than 1.1 with sbottom mass...
