Production of the neutral top-pion πt0in association with a high-pTjet at the LHC

  • In the framework of the topcolor-assisted technicolor (TC2) model, we study the production of the neutral top-pion πt0in association with a high-pTjet at the LHC, which proceeds via the partonic processes gg→πt0g, gq→πt0q, qq→πt0g, gb(b)→πt0b(b), and bb→πt0g. We find that it is very challenging to detect the neutral top-pion πt0via the process pp→πt0+jet+X→tt+jet+X, while the possible signatures of πt0might be detected via the process pp→πt0+jet+X→(tc+tc)+jet+X at the LHC.

    Production of the neutral top-pion πt0in association with a high-pTjet at the LHC

      Corresponding author:YUE Chong-Xing,

      Abstract:

      In the framework of the topcolor-assisted technicolor (TC2) model, we study the production of the neutral top-pion πt0in association with a high-pTjet at the LHC, which proceeds via the partonic processes gg→πt0g, gq→πt0q, qq→πt0g, gb(b)→πt0b(b), and bb→πt0g. We find that it is very challenging to detect the neutral top-pion πt0via the process pp→πt0+jet+X→tt+jet+X, while the possible signatures of πt0might be detected via the process pp→πt0+jet+X→(tc+tc)+jet+X at the LHC.
