28. Resonance contribution of scalar color octet to $t \bar{t}$ production at the LHC in the minimal four color quark-lepton symmetry model

Abstract

The scalar color octet contribution to the resonance $t\bar{t}$-pair production at the LHC is calculated and analysed with account of the one loop effective two gluon vertex. It is shown that this contribution from the scalar color octet $F_2$ predicted by the minimal model with the four color quark-lepton symmetry is for $\sqrt{s}=13$ TeV of about a few percents for $750 < m_{F_2} < 1800$ GeV and can exceed 10% for $400 < m_{F_2} < 750$ GeV. It is also pointed out that the search for the scalar octet $F_2$ as the resonance in the dijet mass spectra seems to be difficult because of the smallness of its one loop effective two gluon interaction., Comment: 12 pages, 5 figures, accepted for publication in Modern Physics Letters A

29. Mass limits for the chiral color symmetry $G'$-boson from LHC dijet data

High Energy Physics - Phenomenology
Abstract

The contributions of $G'$-boson predicted by the chiral color symmetry of quarks to the differential dijet cross-sections in $pp$-collisions at the LHC are calculated and analysed in dependence on two free parameters of the model, the $G'$ mass $m_{G'}$ and mixing angle $\theta_G$. The exclusion and consistency $m_{G'}-\theta_G$ regions imposed by the ATLAS and CMS data on dijet cross-sections are found. Using the CT10 (MSTW~2008) PDF set we show that the $G'$-boson for $\theta_G=45^{\circ}$, i.e. the axigluon, with the masses $m_{G'} < 2.3 \,\, (2.6) \,\, \mbox{TeV}$ and $m_{G'} < 3.35 \,\, (3.25) \,\, \mbox{TeV}$ is excluded at the probability level of $95\%$ by the ATLAS and CMS dijet data respectively. For the other values of $\theta_G$ the exclusion limits are more stringent. The $m_{G'}-\theta_G$ regions consistent with these data at $CL=68\%$ and $CL=90\%$ are also found., Comment: 13 pages, 3 figures, accepted for publication in Modern Physics Letters A

49. The chiral color symmetry of quarks and $G'$-boson contributions to charge asymmetry in $t \bar t$-production at the LHC and Tevatron

Abstract

The contributions of $G'$-boson predicted by the chiral color symmetry of quarks to the charge asymmetry $A_C(p p \to t\bar{t})$ in $t \bar{t}$ production at the LHC and to the forward-backward asymmetry $A_{\rm FB}(p\bar{p} \to t\bar{t})$ in $t\bar{t}$ production at the Tevatron are calculated and analysed in dependence on two free parameters of the model, the $G'$ mass $m_{G'}$ and mixing angle $\theta_G$. The $m_{G'} - \theta_G$ regions of $1 \sigma$ consistency with the CMS data on the cross section $\sigma(pp \to t\bar{t})$ and on the charge asymmetry $A_C(p p \to t\bar{t})$ are found and compared with those resulted from the CDF data on the cross section $\sigma(p\bar{p} \to t\bar{t})$ and on the forward-backward asymmetry $A_{\rm FB}(p\bar{p} \to t\bar{t})$ of $t \bar{t}$ production at the Tevatron with account of the current SM predictions for $A_{\rm FB}(p\bar{p} \to t\bar{t})$., Comment: 11 pages, 3 figures, accepted for publication in Modern Physics Letters A; v2: corrected misprint, added references

50. Chiral density waves in quark matter within the Nambu--Jona-Lasinio model in an external magnetic field

Abstract

A possibility of formation of static dual scalar and pseudoscalar density wave condensates in dense quark matter is considered for the Nambu--Jona-Lasinio model in an external magnetic field. Within a mean-field approximation, the effective potential of the theory is obtained and its minima are numerically studied; a phase diagram of the system is constructed. It is shown that the presence of a magnetic field favors the formation of spatially inhomogeneous condensate configurations at low temperatures and arbitrary non-zero values of the chemical potential., Comment: 13 pages, 4 figures
