We introduce a methodology and investigate the feasibility of measuring quantum properties tau lepton pairs in $H \to \tau^+ \tau^-$ decay at future colliders. In particular, observation entanglement, steerability violation Bell inequalities are examined for ILC FCC-ee. find that detecting correlation crucially relies on precise reconstruction rest frame simple kinematics does not suffice due to finite energy resolution colliding beams detectors. To correct mismeasurements, log-likelihood...
This is the third out of five chapters final report [1] Workshop on Physics at HL-LHC, and perspectives HE-LHC [2]. It devoted to study potential, in search for Beyond Standard Model (BSM) physics, High Luminosity (HL) phase LHC, defined as $3~\mathrm{ab}^{-1}$ data taken a centre-of-mass energy $14~\mathrm{TeV}$, possible future upgrade, Energy (HE) $15~\mathrm{ab}^{-1}$ $27~\mathrm{TeV}$. We consider large variety new physics models, both simplified model fashion more model-dependent one....
We present version 2.3 of SModelS, a public tool for the fast reinterpretation LHC searches new physics on basis simplified-model results. The main features are database update with latest available experimental results full Run 2 luminosity, comprising in particular large variety electroweak-ino searches, and ability to combine likelihoods from different analyses. This enables statistically more rigorous constraints opens way global likelihood analyses searches. impact is demonstrated...
Electroweak-inos, superpartners of the electroweak gauge and Higgs bosons, play a special role in supersymmetric theories. Their intricate mixing into chargino neutralino mass eigenstates leads to rich phenomenology, which makes it difficult derive generic limits from LHC data. In this paper, we present global analysis constraints for promptly decaying electroweak-inos context minimal standard model, exploiting SMODELS software package. Combining up 16 ATLAS CMS searches electroweak-ino...
A bstract Hidden sectors are ubiquitous in supergravity theories, strings and branes. Well motivated models such as the Stueckelberg hidden sector model could provide a candidate for dark matter. In models, communicates with visible via exchange of photon (dark Z ′) while matter is constituted Dirac fermions sector. Using data from collider searches precision measurements SM processes well most recent limits direct indirect detection experiments, we perform comprehensive scan over wide range...
In this paper we review the physics opportunities at linear $e^+e^-$ colliders with a special focus on high centre-of-mass energies and beam polarisation, take fresh look various accelerator technologies available or under development and, for first time, discuss how facility equipped technology mature today could be upgraded of tomorrow to reach much higher and/or luminosities. addition, will detectors alternative collider modes, as well beyond-collider experiments R\&D facilities part...
In this work, we aim to provide a comprehensive and largely model independent investigation on prospects detect long-lived multiply charged particles at the LHC. We consider with spin 0 $\frac{1}{2}$, electric charges in range $1 \le |Q/e| 8$, which are singlet or triplet under $SU(3)_C$. Such might be produced as particle-antiparticle pairs propagate through detectors, form positronium(quarkonium)-like bound state. both possibilities estimate lower mass bounds new particles, that can...
A bstract SM odel S is a public tool for fast reinterpretation of LHC searches new physics based on large database simplified model results. While previous versions were limited to models with $$ {\mathcal{Z}}_2 <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msub> <mml:mi>Z</mml:mi> <mml:mn>2</mml:mn> </mml:msub> </mml:math> -type symmetry, such as R-parity conserving supersymmetry, version 3 can now handle arbitrary signal topologies. To this end, the was fully restructured...
Measurements at particle collider experiments, even if primarily aimed understanding Standard Model processes, can have a high degree of model independence, and implicitly contain information about potential contributions from physics beyond the Model. The Contur package allows users to benefit hundreds measurements preserved in Rivet library test new models against bank LHC date. This method has proven be very effective several recent publications team, but ultimately, for this approach...
The sensitivity of particle-level fiducial cross section measurements from ATLAS, CMS and LHCb to a leptophobic top-colour model is studied. has previously been the subject resonance searches. Here we compare it directly state-of-the-art predictions for Standard Model top quark production also take into account next-to-leading order new physics signal. We make use Contur framework evaluate current measurements, first under default assumption that measurement SM exactly coincide, then using...

We report on our re-calculation of electroweak top-quark pair production in Standard Model extensions with extra heavy neutral and charged spin-1 particles at the LHC. In particular, we allow for flavour-non-diagonal $Z'$ couplings take into account non-resonant beyond. As previous work include NLO QCD corrections match to parton showers POWHEG method fully taking new physics interference effects. consider Sequential Model, Topcolour model as well Third Family Hypercharge featuring...
We investigate the discovery prospects for scalar and fermionic particles with electric charges $1\mathrm{e} \le |Q| 8\mathrm{e}$ that are singlet under $ \mathrm{SU}(2)_L $. calculate lower mass bounds open channel production mode coming from ATLAS/CMS MoEDAL experiments, limits searches positronium-like bound states (closed channel) decaying to two photons. Open by ATLAS CMS more sensitive |Q|\le 5\mathrm{e}$, while closed prevail $6 \mathrm{e} 8\mathrm{e}$. Sensitivity of is comparable...
We present a new calculation of next-to-leading order QCD corrections to electroweak top-quark pair hadroproduction in extensions the Standard Model (SM) with extra heavy neutral and charged spin-1 resonances which considerably extends improves an earlier performed by some us. In particular, we allow for flavor-non-diagonal ${Z}^{\ensuremath{'}}$ couplings take into account nonresonant production SM beyond including contributions $t$-channel $W$ ${W}^{\ensuremath{'}}$ bosons. As result,...
