We perform the most up-to-date comprehensive signal-background analysis for Higgs-pair production in HH ->b ̄b gamma gamma channel at the HL-LHC and HL-100 TeV hadron collider, with the goal of probing the self-coupling of the Higgs boson.

The energy scale of inflation could be as high as 1014 GeV, hence it is a phenomenon at the highest energy scale we may explore. Primordial non-Gaussianities can then be thought of as a 1014 GeV collider (dubbed the cosmological collider), which may be used to probe new particles at the inflationary scale. In this talk I will review recent progress in the cosmological collider program...

The recently announced results on the 21-cm absorption spectrum by the EDGES experiment can place very stringent limits on dark matter annihilation cross sections. We properly take into account the heating energy released from dark matter annihilation from the radiation epoch to the 21-cm observation redshifts in the radiative transfer to compute the evolution of the gas temperature. Our...

We study the phenomenology of a massive graviton G with universal and non-universal (top-philic) couplings to the Standard Model (SM) particles. Such a particle can arise as a warped Kaluza-Klein graviton from a framework of the Randall-Sundrum extra-dimension model. We also consider simplified dark matter models where a dark matter candidate couples to the SM particles via a G mediator. We...

A series of recent results in B physics seem to indicate a coherent pattern of deviations from the Standard Model predictions. I will show how these “anomalies” could naturally be linked to the old, and still open, puzzle of quark and lepton masses, and I will discuss attempts to solve both these problems in terms of physics beyond the Standard Model.

The observed rapid cooling of the neutron star (NS) located at the center of the supernova remnant Cassiopeia A (Cas A) can be explained in the minimal NS cooling scenario. This consequence may be changed if there exists an extra cooling source, such as axion emission. In this work, we study the Cas A NS cooling in the presence of axion emission, taking account of the temperature evolution in...

The dark matter (or some of it) could exist in a form that decays to neutrinos at cosmologically late times. Proposed experiments searching for the cosmic neutrino background, such as PTOLEMY, could be sensitive to this scenario. We discuss the signals allowed at such an experiment given cosmological constraints.

The search for boosted dark matter, which often arises in two-component dark matter scenarios, has received rising attention as an alternative dark matter search strategy. I will discuss phenomenology of boosted dark matter at neutrino detectors including Super/Hyper Kamiokande, focusing on the case where such boosted dark matter scatters off target material inelastically to a heavier unstable...

I will talk about two distinct ideas connected by the introduction in particle phenomenology of disordered systems with a large number of degrees of freedom. First I will show how freeze-in dark matter can solve the hierarchy problem. Then I will discuss how hidden sectors with a large number of new particles can hide at colliders.

A continuum limit of the clockwork mechanism provides a useful picture to understand extra dimensions. The Generalized Linear Dilaton model (GLD) realizes the continuum clockwork with varying clockwork gear masses. A special point of GLD is the linear dilaton model (LD) which has been discussed from the type II little string theory. In this talk, I will discuss a possible UV completion of GLD...

We determine the strong coupling constant alpha_s from the static QCD potential by matching a theoretical calculation with lattice QCD computation. We adopt a new theoretical framework where we subtract the renormalon uncertainties, which limit the accuracy of perturbation theory, based on OPE. This allows us to take a considerably wider fitting range than ordinary perturbation theory, which...

We propose a novel method for measuring the triple Higgs coupling at the LHC. We choose the hh -> (b b)(l+l- MET) process, as a concrete example, which is least investigated due to huge backgrounds. The method relies on two new kinematic functions, Topness and Higgsness, which respectively characterize features of ttbar (major background) and hh events. It leads to a surprisingly high signal...
