3C... LHAGLUE Interface to LHAPDF library of modern parton
4C... density functions (PDF) with uncertainties
5C...
6C...Authors for v4: Dimitri Bourilkov, Craig Group, Mike Whalley
7C...
8C...Authors for v3: Dimitri Bourilkov, Craig Group, Mike Whalley

10C...Author for v1 and v2: Dimitri Bourilkov bourilkov@mailaps.org
11C... University of Florida
12C...
13C...HERWIG interface by Dimitri Bourilkov and Craig Group
14C...
15C...New numbering scheme and upgrade for LHAPDF v2.1
16C...by Dimitri Bourilkov and Mike Whalley
17C...
18C...For more information, or when you cite this interface, currently
19C...the official reference is:
20C...D.Bourilkov, "Study of Parton Density Function Uncertainties with
21C...LHAPDF and PYTHIA at LHC", hep-ph/0305126.
22C...
23C...The official LHAPDF page is:
24C...
25C... http://durpdg.dur.ac.uk/lhapdf/index.html
26C...
27C...The interface contains four subroutines (similar to PDFLIB).
28C...It can be used seamlessly by Monte Carlo generators
29C...interfaced to PDFLIB or in stand-alone mode.
30C...
31C... For initialization (called once)
32C...
33C... PDFSET(PARM,VALUE)
34C...
35C... For the proton/pion structure functions
36C...
37C... STRUCTM(X,Q,UPV,DNV,USEA,DSEA,STR,CHM,BOT,TOP,GLU)
38C...
39C... For the photon structure functions
40C...
41C... STRUCTP(X,Q2,P2,IP2,UPV,DNV,USEA,DSEA,STR,CHM,BOT,TOP,GLU)
42C...
43C... For statistics ON structure functions (under/over-flows)
44C...
45C... PDFSTA
46C...
47C...This interface can be invoked in 3 ways depending
48C...on the value of PARM(1) provided by the user when
49C...calling PDFSET(PARM,VALUE):
50C...
51C... For PYTHIA: PARM(1).EQ.'NPTYPE'
52C... (this is set automatically by PYTHIA)
53C...
54C... For HERWIG: PARM(1).EQ.'HWLHAPDF'
55C... (set by the USER e.g. in the main program like this:
56C... AUTPDF(1) = 'HWLHAPDF'
57C... AUTPDF(2) = 'HWLHAPDF' )
58C...
59C... For Stand-alone: PARM(1).EQ.'DEFAULT'
60C... (can be used for PDF studies or when interfacing
61C... new generators)
62C...
63C...The LHAPDF set/member is selected depending on the value of:
64C...
65C... PYTHIA: ABS(MSTP(51)) - proton
66C... ABS(MSTP(53)) - pion
67C... ABS(MSTP(55)) - photon
68C...
69C... HERWIG: ABS(INT(VALUE(1)))
70C...
71C... STAND-ALONE: ABS(INT(VALUE(1)))
72C...
73C...
74C... CONTROL switches:
75C... ==================
76C...
77C... THE LOCATION OF THE LHAPDF LIBRARY HAS TO BE SPECIFIED
78C... AS DESCRIBED BELOW (the rest is optional)
79C...
80C... if the user does nothing, sensible defaults
81C... are active; to change the behaviour, the corresponding
82C... values of LHAPARM() should be set to the values given below
83C...
84C... Location of the LHAPDF library of PDFs (pathname):
85C... uses common block /LHAPDFC/
86C...
87C... If the user does nothing => default = subdir PDFsets of the
88C... current directory (can be real subdir
89C... OR a soft link to the real location)
90C... If the user sets LHAPATH => supplied by the USER who defines the
91C... path in common block COMMON/LHAPDFC/LHAPATH
92C... BEFORE calling PDFSET
93C...
94C... Other controls:
95C... ===============
96C... use common block /LHACONTROL/
97C...
98C... Collect statistics on under/over-flow requests for PDFs
99C... outside their validity ranges in X and Q**2
100C... (call PDFSTA at end of run to print it out)
101C...
102C... LHAPARM(16).EQ.'NOSTAT' => No statistics (faster)
103C... LHAPARM(16).NE.'NOSTAT' => Default: collect statistics
104C...
105C... Option to use the values for the strong coupling alpha_s
106C... as computed in LHAPDF in the MC generator
107C... (to ensure uniformity between the MC generator and the PDF set)
108C... WARNING: implemented ONLY for PYTHIA in LHAPDFv4
109C...
110C... LHAPARM(17).EQ.'LHAPDF' => Use alpha_s from LHAPDF
111C... LHAPARM(17).NE.'LHAPDF' => Default (same as LHAPDF v1/v3)
112C...
113C... Extrapolation of PDFs outside LHAPDF validity range given by
114C... [Xmin,Xmax] and [Q2min,Q2max]; DEFAULT => PDFs "frozen" at the
115C... boundaries
116C...
117C... LHAPARM(18).EQ.'EXTRAPOLATE' => Extrapolate PDFs on OWN RISK
118C... WARNING: Crazy values can be returned
119C...
120C... Printout of initialization information in PDFSET (by default)
121C...
122C... LHAPARM(19).EQ.'SILENT' => No printout (silent mode)
123C... LHAPARM(19).EQ.'LOWKEY' => Print 5 times (almost silent mode)
124C...
125C...
126C...v5.0 06-Oct-2005 Major change to allow multiset-initializations
127C...v4.0 28-Apr-2005 PDFSTA routine; option to use Alfa_s from LHAPDF
128C...v4.0 21-Mar-2005 Photon/pion/new p PDFs, updated for LHAPDF v4
129C...v3.1 26-Apr-2004 New numbering scheme, updated for LHAPDF v2/v3
130C...v3.0 23-Jan-2004 HERWIG interface added
131C...v2.0 20-Sep-2003 PDFLIB style adopted
132C...v1.0 05-Mar-2003 First working version from PYTHIA to LHAPDF v1
