We propose a model for dark matter and dark radiation, based on a strongly-coupled dark SU(5) gauge theory with fundamental and decuplet dark-quarks. The model supports light dark-baryons, respecting the chiral symmetry, which are electrically neutral but have electromagnetic form factors, and also a light dark-axion. Since the coupling of dark baryons to the standard model particles is...
The evidence for Dark Matter in nature is overwhelming. A particle explanation is both conservative and compelling. Nonetheless, with gravitation its only known experimental signal, general considerations allow the particle’s mass to be anywhere within 41 orders of magnitude below the Planck scale. This range narrows significantly if we propose simple extensions of the Standard Model of...
Upon treating the whole closed-string massless NS-NS sector as stringy graviton fields, Double Field Theory may evolve into `Stringy Gravity'. In terms of an O(D,D) covariant differential geometry beyond Riemann, we present the definitions of the off-shell conserved stringy Einstein curvature tensor and the on-shell conserved stringy Energy-Momentum tensor. Equating them, all the equations of...
We propose new boosted weak gauge boson taggers based upon deep learning. It is shown to have better efficiency over the traditional BDT technique in discriminating W+/W-/Z bosons at the LHC.
We consider the inflation model of a singlet scalar field (sigma field) with both quadratic and linear non-minimal couplings where unitarity is ensured up to the Planck scale. We assume that a Z2 symmetry for the sigma field is respected by the scalar potential in Jordan frame but it is broken explicitly by the linear non-minimal coupling due to quantum gravity. Also, we discuss a novel...
We extend the Standard Model (SM) with parity symmetry, motivated by the strong CP problem and dark matter. In our model, parity symmetry is conserved at high energy by introducing a mirror sector with the extra gauge symmetry, SU(2)R×U(1)R. The charges of SU(2)R×U(1)R are assigned to the mirror fields in the same way as in the SM, but the chiralities of the mirror fermions are opposite to...
In the scenario to solve the cosmological constant problem by scale invariance, it is necessary to spontaneously break the scale invariance. The point is that it must be realized with no fine tuning. I discuss the possiblity in a dynamical model.
In this talk, we present recent highlights of Belle physics results as well as those from the Phase 3 operation of Belle II.
I will review current status of B anomalies related RK() and RD().
We discuss the Neutron Star heating by dark matter accumulation and by the so-called rotochemical heating, based on [arXiv:1905.02991].
