New Higgs Inflation in a No-Scale Supersymmetric SU(5) GUT

John Ellis, Hong-Jian He, Zhong-Zhi Xianyu

Higgs inflation is attractive because it identifies the inflaton with the electroweak Higgs boson. In this work, we construct a new class of supersymmetric Higgs inflationary model…

LHC searches for the CP-odd Higgs by the jet substructure analysis

Ning Chen, Jinmian Li, Yandong Liu +1

The LHC searches for the CP-odd Higgs boson is studied (with masses from 300 GeV to 1 TeV) in the context of the general two-Higgs-doublet model. With the discovery of the 125 GeV…

Probing Gravitational Dark Matter

Jing Ren, Hong-Jian He

So far all evidences of dark matter (DM) come from astrophysical and cosmological observations, due to gravitational interactions of the DM. It is possible that the true DM particl…

Thermalization of gluons with Bose-Einstein condensation

Zhe Xu, Kai Zhou, Pengfei Zhuang +1

We study the thermalization of gluons far from thermal equilibrium in relativistic kinetic theory. The initial distribution of gluons is assumed to resemble that in the early stage…

Collective modes and Kosterlitz-Thouless transition in a magnetic field in the planar Nambu--Jona-Lasino model

Gaoqing Cao, Lianyi He, Pengfei Zhuang

It is known that a constant magnetic field is a strong catalyst of dynamical chiral symmetry breaking in 2+1 dimensions, leading to generating dynamical fermion mass even at weakes…

Radiative Return for Heavy Higgs Boson at a Muon Collider

Nabarun Chakrabarty, Tao Han, Zhen Liu +1

Higgs boson properties could be studied with a high accuracy at a muon collider via the s-channel resonant production. We consider the situation where the center-of-mass energy of…

3.5 keV Galactic Emission Line as a Signal from the Hidden Sector

Ning Chen, Zuowei Liu, Pran Nath

An emission line with energy of $E \sim 3.5$ keV has been observed in galaxy clusters by two experiments. The emission line is consistent with the decay of a dark matter particle wi…

Doubly Charged Lepton from an Exotic Doublet at the LHC

Teng Ma, Bin Zhang, Giacomo Cacciapaglia

We studied the signatures at the LHC of the electroweak SU(2) lepton doublet which embeds a doubly charged lepton. The doubly charged lepton pair and single production rates, which…

LHC Constraints on a Higgs Partner from an Extended Color Sector

R. Sekhar Chivukula, Arsham Farzinnia, Jing Ren +1

We discuss the properties and LHC phenomenology of a potentially discoverable heavy scalar boson ( $s$ ) that arises in the context of the renormalizable coloron model; the model als…
