Revisiting the limits on dark matter annihilation cross-section and decay lifetime in light of electron and positron fluxes
Nagisa Hiroshima, Kazunori Kohri, Partha Kumar Paul +1
We revisit the upper bound on the annihilation cross-section, of a stable dark matter (DM) of mass GeV by considering five different channels: $W^+…
Rephasing Invariant Formula for CP Phase in Kobayashi-Maskawa Parametrization and Exact Sum Rule with Unitarity Triangle
Masaki J. S. Yang
In this letter, we obtain a rephasing invariant formula for the CP phase in the Kobayashi--Maskawa parameterization $δ_{\rm KM} = \arg [ - { V_{ud} \det V_{\rm CKM} / V_{us} V_{ub}…
Gauge coupling unification and proton decay via 45 Higgs boson in SU(5) GUT
Naoyuki Haba, Keisuke Nagano, Yasuhiro Shimizu +1
We study the gauge coupling unification (GCU) and proton decay in a non-supersymmetric SU(5) grand unified theory (GUT) incorporating a 45 representation Higgs field. Our analysis…
Higgs Portal Majorana Fermionic Dark Matter with the Freeze-in Mechanism
Junpei Ikemoto, Naoyuki Haba, Shimizu Yasuhiro +1
We consider a minimal model of fermionic dark matter, in which the Majorana fermion dark matter (DM) couples with the Standard Model (SM) Higgs field through a higher-dimen…
Conditions for Suppressing Dimension-five Proton Decay in Renormalizable SUSY GUT
Naoyuki Haba, Toshifumi Yamada
The SUSY GUT is in severe tension with the experimental bounds on proton partial lifetimes because proton decay mediated by colored Higgsinos (dimension-five proton decay)…
Search for Lepton Flavor Violating Decay at FASER
Takeshi Araki, Kento Asai, Hidetoshi Otono +2
FASER is one of the promising experiments which search for long-lived particles beyond the Standard Model. In this paper, we consider charged lepton flavor violation (CLFV) via a l…
