Charm-quark Yukawa Coupling in $h \to c c ˉ γ$ at LHC

Tao Han, Benjamin Nachman, Xing Wang

It is extremely challenging to probe the charm-quark Yukawa coupling at hadron colliders primarily due to the large Standard Model (SM) background (including $h \to b b ˉ$ ) and th…

Dark Matter Blind Spots at One-Loop

Tao Han, Hongkai Liu, Satyanarayan Mukhopadhyay +1

We evaluate the impact of one-loop electroweak corrections to the spin-independent dark matter (DM) scattering cross-section with nucleons ( $σ_{SI}$ ), in models with a so-calle…

Hidden-Bottom Pentaquarks

Gang Yang, Jialun Ping, Jorge Segovia

The LHCb Collaboration has recently reported strong evidences of the existence of pentaquark states in the hidden-charm baryon sector, the so-called $P_{c} (4380)^{+}$ and $P_{c} (4450)^{+}$ …

The Direct Coupling of Light Quarks to Heavy Di-quarks

Haipeng An, Mark B. Wise

In the limit $m_{Q} > m_{Q} v_{rel} > m_{Q} v_{rel}^{2} ≫ Λ_{QC D}$ hadronic states with two heavy quarks $Q$ should be describable by a version of HQET where the heavy quark is re…

Search for the vectorlike leptons in the U(1) $_{X}$ model inspired by the $B$ -meson decay anomalies

Fang-Zhou Xu, Wenxing Zhang, Jinmian Li +1

We consider the U(1) $_{X}$ model, which can induce the flavor violating couplings through vectorlike fermions and address the observed rare $B$ -meson decay anomalies. To be consisten…

TeV Scale Neutrino Mass Generation, Minimal Inelastic Dark Matter, and High Scale Leptogenesis

Pei-Hong Gu, Hong-Jian He

The seesaw and leptogenesis commonly depend on the masses of same particles, and thus are both realized at the same scale. In this work, we demonstrate a new possibility to realize…

Constraints on millicharged particles with low threshold germanium detectors at Kuo-Sheng Reactor Neutrino Laboratory

TEXONO Collaboration, L. Singh, J. W. Chen +13

Relativistic millicharged particles ( $χ_{q}$ ) have been proposed in various extensions to the Standard Model of particle physics. We consider the scenarios where they are produced at…

Shear viscosity of ultrarelativistic Boson systems in the presence of a Bose-Einstein condensate

Zhengyu Chen, Carsten Greiner, Zhe Xu +1

We calculate for the first time the shear viscosity of ultrarelativistic Boson systems in the presence of a Bose-Einstein condensate (BEC). Two different methods are used. One is t…

De Sitter Quantum Loops as the origin of Primordial Non-Gaussianities

Haipeng An, Mark B. Wise, Zipei Zhang

It was pointed out recently that in some inflationary models quantum loops containing a scalar of mass $m$ that couples to the inflaton can be the dominant source of primordial non…

A potential scenario for the Majorana neutrino detection at future lepton colliders

Yang Zhang, Bin Zhang

The existence of Majorana neutrinos must lead to lepton-number violating processes, and the Majorana nature of neutrinos can only be experimentally verified via lepton-number viola…
