    Long-range forces that couple selectively to particular forms of matter are one of the most historically significant scenarios for physics beyond the Standard Model. They can be studied, depending on the coupling and the range of the interaction, with many different probes, from tabletop experiments to cosmological observations. In this lecture, we discuss some of the experimental methods to...

    The relative abundances of light elements produced during Big Bang Nucleosynthesis (BBN) are highly sensitive to the physics of the primordial universe. Percent-level measurements of these abundances have enabled precision cosmology from BBN; to match this level of precision in theoretical calculations, careful handling of uncertainties arising from nuclear reaction cross sections is of...

    I shall present an analytical derivation of the chiral symmetry breaking minima in supersymmetric asymptotically-free SU(N) and Sp(N) gauge theories with F flavors of “quarks”, perturbed by Anomaly-Mediated Supersymmetry Breaking. Applying AMSB to the ADS, quantum-modified, s-confining, free magnetic and conformal phases of these theories, we are able to show that almost all of them possess...

    Axions and axion-like particles (ALPs) provide well-motivated solutions to the strong CP problem and constitute compelling dark matter candidates. In this poster, I present complementary strategies for probing axions across a broad mass range using both laboratory-based direct detection and collider phenomenology.

    On the direct detection side, I present results from a dielectric haloscope...

    We present a quantum quadratic gravity inflationary scenario that can accommodate the new cosmological constraints, which have disfavored Starobinsky inflation. The theory is asymptotically free in the ultraviolet, but 1-loop running is found to dynamically lead to slow-roll inflation toward the infrared, which is explored for both flat and cosmological backgrounds. In the former case, the...

    Dark photons are hypothetical dark massive vector gauge bosons that are one of the simplest and best-motivated extensions of the Standard Model. Through a kinetic mixing term, visible photons can resonantly convert into dark photons when the plasma mass of ionized gas equals the dark photon mass $m_{A'}$​. This disappearance of Standard Model photons would leave striking signatures in maps of...

    While cooling down, the early universe is believed to have undergone symmetry breaking phase transitions. One attractive possibility for extending the Standard Model is that these phase transitions are of the first order, as they might be able to produce observable gravitational waves. We consider a dark matter freeze-out mechanism, filtering, where dark matter particles become massive in a...

    Direct-detection analyses typically assume the Standard Halo Model (SHM) with a Maxwell–Boltzmann velocity distribution. However, deviations from this form—especially in the high-velocity tail seen in simulations—are particularly important for single-phonon searches, whose kinematic thresholds make them sensitive to this region. Astrophysical uncertainties in both the velocity distribution and...

    Supernovae provide among the most powerful probes of weakly-coupled new particles in the MeV mass range, where laboratory experiments lose sensitivity. In this work, we constrain the mixing angle $\sin \theta$ of a Higgs mixed scalar to five orders of magnitude below the existing collider bounds ($\sin \theta \sim 10^{-9}$) using an improved supernovae cooling bound and with new decay-based...

    We introduce a two real scalar singlet extension of the two Higgs doublet
    model. We study the vacuum structure, the bounded from below conditions, the restrictions from the oblique parameters S,T and U, as well as the unitarity constraints. We
    submit the model to collider and Dark Matter experimental constraints and explore its allowed parameter space. We compare randomly populated...

    Understanding the particle nature of dark matter remains one of the key challenges in contemporary physics. Although the thermal relic picture provides a natural explanation for the observed dark matter density, the continuing absence of positive signals in direct detection experiments calls into question the simplest WIMP hypotheses. A compelling alternative scenario emerges when dark matter...

    The inconsistency in the measurements of the neutron half-life by bottle and beam experiments is a long-standing problem in particle physics. While both experiments rely on the expected decay channel $n\rightarrow p+e+\bar \nu_e$ , bottle experiments compute the half-life by measuring the number of neutrons as they decay, while beam experiments count the number of emitted protons. The...

    The current ΛCDM model has been successful in explaining large scale structure formation, but observations of small-scale structure deviate from theoretical models, influencing continued study into alternatives to CDM. Strong gravitational lensing is a powerful probe of small-scale dark matter structure and alternative dark matter models that is only dependent on the total underlying...

    The decay of the nuclear isomer Ta-180m has yet to be observed, setting a half-life lower limit of 2.9e17 years. The conditions necessary to detect such a rare event exist only in ultra-clean detectors in a low-background environment, such as the MAJORANA DEMONSTRATOR. In the latest attempt to detect the Ta-180m decay, 17.39 kg of high-purity tantalum disks were placed within the natural...

    As searches for WIMPs approach fundamental sensitivity limits, interest in the more general class of thermal relics has emerged, where these dark matter candidates give rise to clear and testable predictions in small, accelerator-based experiments. The Light Dark Matter eXperiment (LDMX), proposed to operate in End Station A at SLAC, is an electron-beam fixed-target missing-momentum experiment...

    The asymptotic safety paradigm for quantum gravity can be used to provide pre/post-dictions for some of the standard model parameters, such as the mass of the top quark. This prediction depends on the scale of quantum gravity, which is usually presumed to be at the Planck scale. However, requiring compatibility with experimental data and having a UV completion of a theory of gravity coupled to...

    In the context of phenomenological modified gravity, Starobinsky inflation is considered one of the most successful inflationary models. However, from a fundamental physics perspective, it faces a significant naturalness challenge. Compatibility with cosmological observations requires a remarkably strong hierarchy: the R^2 term must be extremely large, while higher-order corrections must be...
