The production of two same-sign W bosons in association with two jets via vector boson scattering (VBS), ssWWjj, is a key probe of the mechanism of electroweak symmetry breaking, with the Higgs boson unitarising the process' cross-section. Longitudinal ssWWjj involves the spin-0 modes of the gauge bosons arising from EWSB, and is very sensitive to BSM physics.
With the Run-2 and Run-3...

A mechanism accommodating baryonic Dark Matter (DM) has been proposed recently [arXiv:2101.02706,arXiv:1810.00880]. This has the advantage of explaining matter-anti-matter imbalance and DM at once, without requiring the proton to be unstable. The DM particles, carrying baryon number, would be produced in $b$-hadron decays, through a t-channel mediator. In this model, $b$-hadron branching...

The ATLAS experiment has been in successful operation at the Large Hadron Collider (LHC) since 2009, collecting data from proton-proton collisions of up to $\sqrt{s}$ = 13 TeV. It is now gearing up to collect its majority of data at the high luminosity LHC. For this, upgrades are underway to face the challenge of a significant increase in number of interactions per bunch-crossing (pile-up),...

Over the last few years, several discrepancies with respect to SM predictions have arisen in studies of exclusive $b\to s \ell^{+}\ell^{-}$ decays, where a b-hadron decays into a specific final state. The interpretation for a significant fraction of these discrepancies is clouded by hadronic uncertainties. Inclusive $b\to s \ell^{+}\ell^{-}$ decays are regarded to be under better theoretical...

A Future Large Hadron electron Collider (LHeC) would allow to collide an intense electron beam with a proton or ion beam from the High Luminosity–Large Hadron Collider (HL-LHC). Preliminary studies suggest that not only a rich physics program in the context of deep-inelastic scattering is possible, but also that several high precision Higgs coupling measurements could be performed.

Observation of the cosmic microwave background radiation (CMBR) by various satellites confirms the Big Bang evolution, inflation and provides important information regarding the early Universe and its evolution with excellent accuracy [1].

A novel approach to the experimental and theoretical study of the properties of QCD matter under the new extreme conditions is discussed. Our simulations demonstrate a possibility to reach the initial temperature over 300 MeV and baryonic charge density exceeding the ordinary nuclear density by a factor of three. Such conditions could be realized in the high luminosity (HL) experiments at LHC...

The measurement of the trilinear Higgs self-coupling is among the primary goals of the high-luminosity LHC and is accessible in Higgs pair production. However, this process is also sensitive to other couplings. While most of them can be well-constrained by single-Higgs measurements, this does not hold true for the coupling between the Higgs and light quarks. We show that the Higgs pair...

For a long time it was conjectured that the large azimuthal anisotropic flow observed in heavy-ion collisions implied early thermalization. After the discovery of azimuthal anisotropic flow in small systems, where it is unclear if there is time for the system to thermalize, it was realized that one can have hydrodynamization, a phenomena in which flow can build up out-of-equilibrium (chemical...

Within the Phase-II upgrade of the LHC, the readout electronics of the ATLAS LAr Calorimeters is prepared for high luminosity operation expecting a pile-up of up to 200 simultaneous pp interactions. Moreover, the calorimeter signals of up to 25 subsequent collisions are overlapping, which increases the difficulty of energy reconstruction. Real-time processing of digitized pulses sampled at 40...

Data is what drives all research forward, regardless of scientific discipline. At the Large Hadron Collider (LHC) in Switzerland, the data stream of registered events can reach about 60 million megabytes per second, making it physically impossible to save all the produced data with current storage technology. This means that data selection has to be performed at an early stage in the...

We study the prospect of determining the CP violating phase in $\tau - $lepton Yukawa coupling at the $e^-p$ Collider (LHeC). The beam energy that we have considered for the electron and proton is 150 GeV and 7 TeV respectively. The Higgs is produced through charged current as well as neutral neutral current process with a focus on the earlier because of the higher cross section. We have...

We probe anomalous HZZ coupling through single Higgs boson production at the Large Hadron electron collider with 60 GeV (7 TeV) of electron (proton) energy.
