    The High Luminosity LHC will be a tremendous opportunity to search for long lived particles (LLPs) from an extended hidden/dark sector, feebly connected to the known SM sector. Such LLP searches will require special detectors, placed far away from the proton-proton collision point and shielded against SM backgrounds. The CODEX-b detector, to be placed behind a thick shielding wall inside the...

    We suggest a new class of models - Fermionic Portal Vector Dark Matter (FPVDM) which extends the Standard Model (SM) with SU(2)_D dark gauge sector. While FPVDM does not require kinetic mixing and Higgs portal. It is based on the Vector-Like (VL) fermionic doublet which couples the dark sector with the SM sector through the Yukawa interaction. The FPVDM framework provides a vector Dark Matter...

    t has been proposed that, in the large radius compactification (LRC) scenario, the Kaluza-Klein states might be considered as dark matter (DM) candidates. The universal extra dimension (UED) hypothesis, together with the LRC paradigm, holds the prospect of observing KK states at LHC if masses lie in the accessible LHC energy scale. If observed, they might be possible DM candidates, provided...

    Anti-quark nuggets, AQNs, (ZHITNITSKY, 2003), have been suggested to solve the dark matter (DM) and the missing antimatter problem in the universe, and have been proposed as an explanation of various observations.

    Their size is in the μm range and their density equal to the nuclear density with an expected flux of about 1 / km2 / year. For the typical velocity of DM constituents (~250...

    In this talk, I will review the importance of "Gauge invariance" in the search for Dark matter at the High Energy Collider including LHC.

    The major topics I will include will be
    1) The limit of effective field theory / simplified model approach at the High Energy collider
    2) Dark matter showering at the High Energy collider

    We explore the parameter space of the phenomenological Minimal Supersymmetric Standard Model (pMSSM) with a light neutralino thermal dark matter (M ̃χ01 ≤ Mh/2) that is consistent with current collider and astrophysical constraints. We identify that a narrow region with light Higgsinos having masses between 125-160 GeV survives the present constraints for the μ < 0 scenario, including the...

    Dark matter bound states may exist within the dark sector, characterized by a substantial dark force. Depending on the spins and parity properties of the force carriers, Standard Model particles may primarily couple with either the lowest or excited bound states. We discuss the associated collider signatures at the LHC for various simplified models.

    The 2HDMa model is one of the main models used in the Dark Matter searches at the LHC. So far, all the 2HDMa benchmarks used by the LHC experiments feature a Type-II Yukawa sector with degenerate Higgses ($m_A=m_H=m_{H^{\pm}}$). The latter implies, together with the fact that flavour observables put lower bounds on the mass of the charged Higgses, that the $A/H/H^{\pm}$ bosons are all...

Three signal regions were defined as bins in the $\text{E}_\text{T}^{\text{miss}}$ significance, and the search was performed by scanning across the...

    Belle II has a unique reach for a broad class of models that postulate the existence of dark matter particles in the MeV-GeV mass range. One scenario is a model which involves inelastic dark matter, consisting of two dark matter states with a mass splitting between them and the presence of a dark Higgs boson. This model has a signature of up to two displaced vertices, one from the resonant...

In particular we find that for...

    The Hidden Valley scenario consists of a set of models where the Standard Model is accompanied by a Hidden Sector and connected with it via a heavy mediator or a weak coupling. If realised in nature, the Hidden Valley scenario may result in unusual and little-studied phenomena at the LHC. Under the assumption of a QCD-like confining dark sector, novel experimental signatures emerge,...

    Singlet-Triplet Fermionic Model ($\nu$STFM) with an extended fermion and Higgs sector is a well motivated model which explains both neutrino masses and dark matter (DM). Two of the triplet $\rho_{1,2}$ and singlet fermionic fields $N_{1,2}$ contribute to neutrino mass generation via seesaw mechanism, while, the remaining triplet $\rho_3$ and singlet $N_3$ fields are the constituents of the...

    The existence of a new type of non-baryonic matter in the Universe, also called Dark Matter (DM), is supported by compelling astrophysical and cosmological evidence. Considerations on its measured relic density favour the hypothesis that Dark Matter is composed primarily of Weakly Interacting Massive Particles (WIMPs). Unfortunately, numerous experiments targeting the detection of these DM...

    Recasting is an extremely powerful tool to derive limits on new physics
    models. With so many NP models at our disposal, recasting makes it easy to use the limits derived on certain models by experimental searches, to
