Determining Strong Phase of Meson Decay Amplitude using Process

Kaoru Hagiwara, Hiroyuki Ishida, Toshifumi Yamada +1

To measure the helicity of a spin-1 meson from the triple vector product of the three-momenta of its decay products, one needs information about the strong phase of the decay ampli…

Doubly-heavy tetraquarks

Gang Yang, Jialun Ping, Jorge Segovia

In the framework of the chiral quark model along with complex scaling range, we perform a dynamical study on the low-lying -wave doubly-heavy tetraquark states ($QQ\bar{q}\bar{q…

model from

Tianjun Li, Junle Pei, Fangzhou Xu +1

We propose the model arising from breaking. One family of the Standard Model (SM) fermions arises from two representations an…

Calculation of anisotropic transport coefficients for an ultrarelativistic Boltzmann gas in a magnetic field within a kinetic approach

Zhengyu Chen, Carsten Greiner, Anping Huang +1

According to the Kubo formulas we employ the (3+1)-d parton cascade, Boltzmann approach of multiparton scatterings (BAMPS), to calculate the anisotropic transport coefficients (she…

Kinetic approach to a relativistic BEC with inelastic processes

Richard Lenkiewicz, Alex Meistrenko, Hendrik van Hees +3

The phenomenon of Bose-Einstein condensation is investigated in the context of the Color-Glass-Condensate description of the initial state of ultrarelativistic heavy-ion collisions…

Discussions on the Line-shape of Resonance

Qin-Fang Cao, Hong-Rong Qi, Yu-Fei Wang +1

A careful reanalysis is made on processes, aiming at resolving the apparent conflicts between Belle and BESIII data above th…

Sensitivity to neutrino-antineutrino transitions for boron neutrinos

S. J. Li, J. J. Ling, N. Raper +1

Neutrino-antineutrino conversion is an important new physics process. The observation of this phenomenon could indicate total lepton number violation and potential CPT-violation. S…

Search for a generic heavy Higgs at the LHC

Xin Chen, Yue Xu, Yongcheng Wu +6

A generic heavy Higgs has both dim-4 and effective dim-6 interactions with the Standard Model (SM) particles. The former has been the focus of LHC searches in all major Higgs produ…

Triply-heavy baryons in a constituent quark model

Gang Yang, Jialun Ping, Pablo G. Ortega +1

A constituent quark model, which has recently been successfully applied to the study of heavy quarkonium properties such as its spectrum but also a diverse array of observables rel…

Mass Correction to Chiral Kinetic Equations

Ziyue Wang, Xingyu Guo, Shuzhe Shi +1

We study fermion mass correction to chiral kinetic equations in electromagnetic fields. Different from the chiral limit where fermion number density is the only independent distrib…

Probing the Scale of New Physics in the Coupling at Colliders

John Ellis, Shao-Feng Ge, Hong-Jian He +1

The triple neutral gauge couplings are absent in the Standard Model (SM) at the tree level. They receive no contributions from dimension-6 effective operators, but can arise…

The PeV-Scale Split Supersymmetry from Higgs Mass and Electroweak Vacuum Stability

Waqas Ahmed, Adeel Mansha, Tianjun Li +3

The null results of the LHC searches have put strong bounds on new physics scenario such as supersymmetry (SUSY). With the latest values of top quark mass and strong coupling, we s…
