The neutrino fog represents a fundamental irreducible sensitivity limit for dark matter direct detection arising from coherent elastic neutrino-nucleus scattering (CEvNS). We present a precision calculation of the neutrino fog for spin-independent (SI), spin-dependent proton-coupled (SDp), and spin-dependent neutron-coupled (SDn) WIMP interactions on a natural xenon target, derived by matching...

Warm dark matter (WDM) particles lighter than O(keV) are excluded at high significance because their early free-streaming strongly suppresses the formation of small-scale structure. However, recent work has suggested that introducing a small fraction of cold dark matter (CDM) with a blue-tilted isocurvature can counteract this suppression, potentially allowing lighter WDM candidates. In this...

The singlet-doublet fermion model of dark matter is an economical weak-scale dark matter model, which realizes the dark matter abundance through interactions with the weak bosons of the Standard Model. Depending on the size of the Yukawa couplings in the model, the dark matter relic abundance can be realized via freeze-out (including co-annihilation), co-scattering, freeze-in, or a super WIMP...

Ultralight dark matter with quadratic couplings to the Standard Model need not have a homogeneous local profile. Scattering on macroscopic bodies can distort the field configuration near Earth and, for sufficiently large couplings, the atmosphere acts as an efficient shield. I will discuss this effect in the context of clock searches and show that space-based platforms offer a natural way...

Leveraging the joint QCD and QED factorization of DIS, with its improved sensitivity and reduced uncertainties in radiative corrections, opens new windows on the possibility of exotic particle emission, such as weakly coupled particles originating from a dark or hidden sector. Measurements of the cross-section would provide evidence through anomalous energy loss, as opposed to bump hunt or...

We propose a minimal and natural dark-sector framework in which dark matter is composed of magnetic monopoles coupled to a light axion field. Through the Witten effect, the axion background induces electric charge on the monopoles, turning them into dyons that in turn modify the axion potential. This monopole-dependent axion mass provides a simple, radiatively stable mechanism for dark-sector...

This talk will explore effective operator models where new light exotic (LEX) states interact with the Standard Model (SM) through the W-gluon portal. Operators included in this talk will contain LEX states with non-trivial representations under the SM gauge groups that couple to at least one W boson and one gluon. The W-gluon portal introduces new single production collider modes and...

The presence of mixed ’t Hooft anomalies between zero and one-form symmetries could further constrain the possible low energy phases of gauge theories. By first constructing the full global symmetry group that acts faithfully on the fermions, we compute all the 't Hooft anomalies in the UV regime, which include mixed anomalies between one-form and zero-form symmetries, for a large class of...

We present the first complete two-loop calculation of the electric and chromo-electric dipole moments of the light quarks and the gluon, as well as contributions to CP-violating lepton-quark interactions, in the unconstrained two-Higgs doublet model. We include the most general Yukawa interactions of the Higgs doublets with the Standard Model fermions up to quadratic order, and allow for...

The diphoton decay channel of the Higgs boson provides a clean experimental signature despite its small branching ratio. At high Higgs transverse momenta, the signal-to-background ratio improves considerably, though with lower statistics. This phenomenological study aims to enhance the separation of the Higgs signal from the diphoton background in this high pT regime using event-level...
