Neutrino CP phases from sneutrino chaotic inflation
Abstract We study if the minimal sneutrino chaotic inflation is consistent with a flavor symmetry of the Froggatt–Nielsen type, to derive testable predictions on the Dirac and Majorana CP violating phases, δ and α. For successful inflation, the two...

Screening in perturbative approaches to LSS
Abstract A specific value for the cosmological constant Λ can account for late-time cosmic acceleration. However, motivated by the so-called cosmological constant problem(s), several alternative mechanisms have been explored. To date, a host of...

A universal constraint on the infrared behavior of the ghost propagator in QCD
Abstract With proposing a unified description of the fields variation at the level of generating functional, we obtain a new identity for the quark–gluon interaction vertex based on gauge symmetry, which is similar to the Slavnov–Taylor Identities...

Phenomenological QCD equations of state for neutron star mergers
Abstract Thermal QCD equations of state at high baryon density are sensitive to the phase structure and the resulting excitation modes. The leading contribution at low temperature can be either ∼ ...

Local and global Λ polarization in a vortical fluid
Abstract We compute the fermion spin distribution in the vortical fluid created in off-central high energy heavy-ion collisions. We employ the event-by-event (3+1)D viscous hydrodynamic model. The spin polarization density is proportional to the...

QCD Matter Physics at FAIR
Abstract The Compressed Baryonic Matter (CBM) experiment will be one of the major scientific pillars of the future Facility for Antiproton and Ion Research (FAIR) in Darmstadt. The goal of the CBM research program is to explore the QCD phase diagram ...

Hunting for exotic doubly hidden-charm/bottom tetraquark states
Abstract We develop a moment QCD sum rule method augmented by fundamental inequalities to study the existence of exotic doubly hidden-charm/bottom tetraquark states made of four heavy quarks. Using the compact diquark–antidiquark configuration, we...

Asymptotically flat scalar, Dirac and Proca stars: Discrete vs. continuous families of solutions
Abstract The existence of localized, approximately stationary, lumps of the classical gravitational and electromagnetic field – geons – was conjectured more than half a century ago. If one insists on exact stationarity, topologically trivial...

A model of spontaneous CP breaking at low scale
Abstract We introduce a CP symmetric model where masses of fermions are given by dimensional-5 operators, and CP is spontaneously broken at TeV scale. The unique feature of the model is that new CP symmetric gauge sector coexists with new CP...

Combination of searches for heavy resonances decaying to WW, WZ, ZZ, WH, and ZH boson pairs in proton–proton collisions at s = 8 and 13 TeV
Abstract A statistical combination of searches is presented for massive resonances decaying to WW, WZ, ZZ, WH, and ZH boson pairs in proton–proton collision data collected by the CMS experiment at the LHC. The data were taken at centre-of-mass...

Fisher information and quantum state estimation of two-coupled atoms in presence of two external magnetic fields
Abstract We consider a quantum system of an atom-atom interaction in the presence of two external magnetic and classical fields in x, and z directions. The dynamical behavior of single atom quantum quantifiers such as the atomic Wehrl entropy,...
