Quantum Computers will constrain the Equation of State of Neutron Stars

This paper outlines a theoretical framework and demonstrates a proof-of-concept simulation using quantum computing to solve the sign problem in Lattice QCD at finite chemical potential, aiming to determine the Equation of State of neutron stars and constrain their static observables in preparation for third-generation gravitational wave detection.

Probing dark matter through charged Higgs pair production at future multi-TeV muon colliders: A machine-learning analysis

This paper investigates the potential of future multi-TeV muon colliders to probe dark matter within the Inert Doublet Model via charged Higgs pair production, demonstrating that machine-learning techniques significantly enhance signal sensitivity over traditional cut-based methods to achieve statistical significance exceeding 5σ5\sigma for viable benchmark points.

Inflation with Nieh-Yan-like terms in metric-affine gravity

This paper investigates single-field slow-roll inflation within metric-affine gravity featuring Nieh-Yan-like terms, demonstrating that specific non-minimal couplings can render sub-Planckian field values viable and resolve observational tensions in both quartic and quadratic Palatini inflation models by adjusting the effective Nieh-Yan coupling.

Di-decay signature of new physics particles at intensity frontier experiments

This paper proposes a discovery strategy for Intensity Frontier experiments that utilizes "di-decay" events, where pairs of feebly interacting particles decay within the detector, to reconstruct invariant mass and distinguish between otherwise indistinguishable new physics models, demonstrating the potential of this approach for facilities like SHiP, Belle II, and Downstream@LHCb.

Consistent Scattering Amplitudes, Yang-Mills, the Higgs Mechanism and the EFTs Beyond

This paper derives fundamental constraints on unitary, local, and perturbative SS-matrices in 4D to reconstruct the complete structure of massless and massive scattering amplitudes, demonstrating that the consistency of massive vector boson scattering necessitates standard Yang-Mills Lie algebra properties and the Higgs mechanism for full unitarization while charting a broader landscape of effective field theories.
